Perfect for anyone who wants to be gently cared for and lulled to sleep by a warm, devoted stepbrother figure.

After a long, exhausting day, your devoted younger stepbrother is there to help you unwind and drift off to sleep. He stays close through the night, offering gentle words and quiet comfort as you share a bed. Soft ambient sounds—a music box, a flowing river, night insects, and rain—wrap around you as you relax into sleep.

Ryo (涼)Stepbrother

23 years old, birthday July 22nd (Cancer), serious and gentle by nature. He is your stepbrother. You share no blood relation; you became siblings through your parents' remarriage. With your parents often busy, the two of you grew up supporting each other. When you got a job in Tokyo, you two lived apart for a while, but he later followed you there, and you began living together again. Ryo has loved you for as long as he can remember, and he wants to support you as you work hard.

★★★★★A gentle bedtime cuddle that heals even your heart!!🌐 AI translated · JA

I've been waiting forever for an all-ages bedtime-cuddle work like this~ I seriously want so many more of these! Circle-san, your talent for making healing works is just too genius, I'm literally crying... how do you understand this so well!? This is the best, I love it so much!! This is a work I want to listen to over and over, on tired days or lonely nights. Yubinaga-san's soft, gentle voice fits Ryo-kun perfectly, and his calm tone and the way he whispers feel so soothing — it's such a perfect match for a bedtime-cuddle work. Ryo-kun is just so kind through and through; the way he immediately notices even the smallest changes in his sister when she comes home tired from work and stays close to her, the way he's always on her side no matter what and accepts her completely, really hits deep... Just listening to his words makes me want to cry, and makes me feel like it's okay for me to be here (tears). I really love this kind of warmth in everyday life and the comfort of spending time together like this. Also, the relationship of being a step-brother with no blood ties is so perfectly balanced — there's the sense of security of being family (yeah), but also a sudden sweetness that makes your heart skip a beat, and this sense of distance is just so, so good... I mean, a little brother like this is a bit dangerous, isn't he~ before you know it you're completely won over, and it feels like you'll be swept along entirely at Ryo-kun's pace lol. The sleep induction is amazing too!! And the bonus sleeping-breath track comes in several versions with different ambient sounds, which I really appreciate! As a hardcore ASMR lover, I'm so happy... Circle-san really is a god (saying it again). Even though it's a track meant to help you fall asleep, my desire to listen all the way through kept fighting a fierce battle with overwhelming sleepiness the whole time lol (30-minute sleeping breath track). And then that confession-like line at the end, followed by the goodnight kiss — that's just unfair too... I can only hope for a sequel with all my heart! I really want to know what happens next!! Hey, should we stop being siblings already......? (jk) Thank you so much, Circle-san, for delivering such a wonderful, healing work, and Yubinaga-san, for playing Ryo-kun~!!

★★★★★I was so healed by kind Ryo-kun!🌐 AI translated · JA

Ryo-kun is such a kind boy, I was really moved. I don't actually have a little brother... yet memories I never had kept coming back to me. Even though I've embraced my role as the older sister, it's frustrating that I can't show any dignity as one when Ryo-kun is such a perfect catch. Please spoil me more (greedy). The fact that he sees through me so well he even understands the feelings I'm hiding...! He's such a kind little brother (T_T) tears of joy. From the jacket I imagined a cute, gentle atmosphere, but Ryo-kun has such a big build... hmm... Thank you for that. The sleeping breath in chapter 4-2! Is it really okay for me to listen to this? Isn't this some kind of crime? Is this legal? It feels like it might be breaking some law, but it's fine, right, to listen? Because we're siblings after all. Right! Chapter 4-3 Even if we stay siblings, isn't it fine for our relationship to progress a bit? As the older sister, I think so... but what do you think, Ryo-kun? I'll be waiting for your reply. Yubinaga-san's little brother was really great. He had warmth, the cuteness of a little brother, and the charm of a man — it was perfect! I usually prefer older love interests, but this made me realize younger ones are great too. I'm someone who barely cares about sound quality at all, but I love the sound in Nakusonneko-dan's works. (It's hard to put into words exactly why I like it.) I know binaural audio is just that kind of thing, but it really conveyed the feeling that Ryo-kun was right there beside me! This is a work I want to recommend to anyone who wants to feel healed or who's tired.

★★★★★For sleepless nights, for a tired heart and body🌐 AI translated · JA

I had been really looking forward to Yubinaga-san's all-ages bedtime work. It's just too good. I think it might help me sleep better than sleeping pills. Within seconds of pressing play, "This tone of Yubinaga-san's is seriously going to put me to sleep" is what I felt. I think Yubinaga-san's voice has something like alpha waves or 1/f fluctuation — some quality that genuinely relaxes the heart. First of all, being called "nee-san" (older sister) is just too much. Yes, it's adorable. He says so many words that melt away a tense heart, and he's just so kind overall. He praises me for working hard, and Ryo-kun's cuteness and his hugs just blow all my fatigue away. And he even says I'm "the cutest in the world"! But you're the cutest one, you know?! I desperately want a little brother like this. Totally smitten, smitten, smitten. The sleep-induction Track 4-1 flows into the 30-minute main sleeping-breath Track 4-2. You might accidentally fall asleep during the induction part without realizing it. It was me (the listener), determined to listen all the way through, versus Yubinaga-san's sleeping breath — a battle stacked against the listener, but there were a few points where I woke up a bit, so I barely managed to make it to the end. If you can stay awake almost until the very end, you're definitely still conscious (personal opinion). I listened with the resolve not to fall asleep and barely made it to the end, so if you play this at actual bedtime, you're guaranteed to lose. In fact, the second time I listened, I fell asleep easily and slept soundly until morning lol. The bonus sleep track (with sound effects) is, like Track 4-2, mainly centered on the sleeping breath, and it's a luxurious track where you can choose the background sound effect while still listening to Yubinaga-san's breathing. Being able to choose a different background sound effect each day is such a nice touch. Personally I have trouble sleeping, so I've added this to my bedtime playlist to help improve my sleep quality. Thank you for such a practical and wonderful work.

★★★★★This might actually be best listened to after work!?🌐 AI translated · JA

I was looking forward to this, wanting to feel healed. I listened to it after work, and since he says "welcome home" and "you worked hard today," all my fatigue just disappeared! Thank you so much. Being healed by Yubinaga-san's gentle voice — this is exactly it! Ryo-kun wears glasses, so he had an intellectual impression, and the feeling that he knows about difficult things too is nice, hehe♪ He heals me and I like him a lot. He even cooks meals for me! He bought a recipe book and studied just for that, how is he such a god! So kind and cute! He really does love his sister-in-law so much (heart). He worries about me too, and asks me all sorts of things! He says even my crying face is the cutest in the world — I'm so loved! Ugh... I like him (heart) But when I told him he's cool, him getting embarrassed was just unfair! I like that about him. Saying lots of things to make him happy and embarrassed brings out my inner sadist a bit (*'ω' *) I hope he and his sister-in-law end up becoming lovers like this, go for it Ryo-kun, I'm rooting for you! He really seemed like he's only interested in his sister-in-law. I'm looking forward to some kyaa-worthy developments in the final track too. When you're tired, or when you want to sleep next to someone, this is especially the work I'd recommend. The length of the sleeping breath on the sleep track is incredible — it's a full 30 minutes! You'll definitely pass right out! There's nothing to do but sleep! If you're curious about devoted Ryo-kun, please go ahead and welcome him home (heart) A life where there's food waiting when you get home really is ideal! Thank you, Circle-san, for this all-ages work. I feel so healed (*'ω' *)

★★★★★Wrapped in a gentle, sweet voice… this bedtime cuddle is the best!🌐 AI translated · JA

After working all day and coming home tired, there's a world where a gentle voice says "welcome home" and "you worked hard"... This is exactly what I've been wanting!! As an adult, going back and forth between work and home day after day, you can get through life, but there's this hollow feeling somehow. This work gently fills and heals that hollow place. Since it's all-ages, it promises you can listen with complete peace of mind. He hugs me, spoils me, and my precious, adorable step-brother praises me, saying "You're amazing, you worked so hard, you're amazing." I had wanted a gentle world like this, so I'd been looking forward to it ever since the preview, and I'm so happy it's finally out, thank you! On nights when I feel irritated or my thoughts are spiraling, the way he gently stays close to me is just too healing. It made me feel reassured that it's okay to switch off when I'm with Ryo-kun. Ryo-kun's voice is just so kind in every way. "Come on, just give up already, okay?" is unbearably cute and just the best. He has that cute little-brother quality, but then there's the way he makes you aware of his bigger build, the way his voice suddenly drops a little lower, the breath near your ear — he really makes you feel the "little brother from an older sister's perspective" vibe properly, while also making your heart race here and there; Ryo-kun is just amazing. I thoroughly enjoyed the happiness of being gently and softly wrapped up in Yubinaga-san's voice as he played the role. At the ending, Ryo-kun's line about going "beyond being siblings"... made me imagine what comes after way too much (blush). The sleeping-breath track has excellent sleep-inducing and lulling-to-sleep effects. I fell asleep so many times, and somehow managed to listen all the way through during the daytime. It's a full 30 minutes long, plus there's a bonus track, so I'm no longer afraid of sleepless nights. And also! The wake-up track is a key feature. Instead of "good morning," it's him reassuring you that it's okay if you wake up partway through... that little charm is the best!!! Thank you so much, Nakusonneko-dan and Yubinaga-san.

★★★★★So healing~🌐 AI translated · JA

This was a work perfect for sleep induction, where you can enjoy healing along with just a little bit of heart-fluttering excitement. Yubinaga-san's gentle voice is truly soothing, and just listening to it naturally calms your feelings. It's not just healing — there's also a nice touch of heart-flutter, making for a pleasant kind of stimulation too, which was wonderful. I want to hear more of this conversation... Perfect for when you want to heal from a day's fatigue, or when you want to spend a relaxed moment before bed. This is a work where you can fall asleep happily, wrapped in Yubinaga-san's voice.

★★★★★Tonight too, I'm drifting off to sleep comforted by my little brother-in-law who's always loved me🌐 AI translated · JA

I got hooked by "my favorite kind of sleep-inducing work...!" (heart). Thank you for reeling me in. Ryo-kun's voice was so very calm, and I felt wrapped in gentleness from start to finish. I slept so soundly. To give you an idea, it took me two days and two separate times falling asleep before I even reached the sleep-inducing part (true story). The episodes told throughout the work are so heartwarming, and I love how it's structured so that Ryo-kun's "I love you"s, scattered here and there, come through vividly against that backdrop. I listened again during the daytime, and I was like, "Wait, he was saying THIS while I was asleep (actually asleep)?!" It was hard to keep my composure. Besides the main story with SE, it also comes bundled with a voice-only version and bonus tracks with rain sounds and a babbling brook (plus voice), so I felt it's a work you can enjoy in many different ways. Everyone who's tired from work, let's spend a night being thoroughly pampered by Ryo-kun and get some sleep...

★★★★★I listened after sleeping a lot beforehand🌐 AI translated · JA

Since I'm lulled to sleep by Mr. Yubinaga's voice almost every day, I was 100% certain I'd fall asleep partway through, so for the first listen I wanted to hear it all the way through properly, and I got a solid 10 hours of sleep beforehand. Completely backwards logic, I know. I love naughty situation voice works, but there are times when I just want to be healed and relax, so having an all-ages option is such a blessing. From the very first "welcome home," his voice is gentle and soothing the whole way through. If I came home exhausted from overtime to a cute little brother-in-law like this who made dinner and welcomed me, my fatigue would just vanish. Mr. Yubinaga's "Nee-san" is dangerously high in nutritional value. But adult siblings-in-law wouldn't normally hug, right? Oh wait—he won't let her into the living room until she does? Well, I guess that can't be helped~. *hug* After that, he says he can't see well without his glasses and leans his face in close to whisper in her ear, and he sleeps next to her because she seems unwell, but... isn't this already at a lover's distance??? Am I the one who's wrong? Well, he's sneakily adorable about it so in the end I forgive him anyway... Ryo-kun has no intention of hiding his feelings, so he casually says things like "I love you" and "you're cute," and it's unfair how he makes you conscious of him as a man through his hands and body size while calling her "Nee-san." The way his possessiveness and attachment seep through is the best. The main sleep-inducing track, tr4-2, lets you savor a full 30 minutes of Ryo-kun's sleeping breaths. The sleep-talk scattered in between hits incredibly hard. I was like, "Wait, did he just say he loves me?!" and replayed it at a volume way too loud for bedtime. On top of that, there are four different bonus versions of this track with BGM added. The benefits are amazing. And then, just as you're completely relaxed, tr5 arrives—the effect of the spell to help you forget unpleasant things is outstanding. You end up unable to think about anything but Ryo-kun, and every single thing he does melts you. I love him!!! I said it's great that it's all-ages, but that said, I live for naughty situation voice works, so if a sequel comes out where she and Ryo-kun become lovers, I will absolutely buy it. Please make it happen.

★★★★★I slept so well🌐 AI translated · JA

I bought this immediately because it's an all-ages sleep-inducing voice work by Mr. Yubinaga. I hadn't really heard him voice a younger character before, but his refreshing yet calm tone was really good. Ryo-kun, the little brother-in-law, endlessly comforts the exhausted heroine. He hugs her and affirms her completely, which really soothes a weary heart. He wraps everything up so warmly that I ended up crying. The sleep-inducing part starts from Tr4, and Mr. Yubinaga's voice is incredibly calming... I fell asleep almost immediately while listening lying down. Also, his sleeping breaths are adorable. I plan to keep listening to this whenever I'm feeling down mentally and can't sleep.

★★★★★A magic spell🌐 AI translated · JA

When I saw the preview, I thought, "Mr. Yubinaga's all-ages sleep-lulling work...? A convenient dream...?" and I kept coming back to check the work's page over and over, looking forward to the release day the whole time (;;) The content is about being thoroughly healed and lulled to sleep after the fatigue of daily life, and seeing the 30-minute sleeping-breath track and the generous bonus content focused on sleep induction, I felt the circle's strong determination of "I will make you sleep no matter what!" It's such a lifesaver for those struggling to fall asleep. For anyone exhausted by a hectic life or troubled by sleeplessness, this is a warm work that gently fills the gaps in your heart like cotton wool, and I'd recommend it not only for sleep induction but also for times when your heart feels restless and unsettled. In the conversation scenes, he speaks in a calm tone throughout, and Mr. Yubinaga's soft voice, neither too high nor too low, gave me such a sense of security that I started feeling sleepy even before the sleep-inducing part began. He's skilled at spoiling her and kind, yet a little pushy toward his sister-in-law who can't take care of herself, and he acts as if he wants her to see him not just as a little brother-in-law but as the grown man he's become—I was completely at the mercy of this slightly mischievous, utterly calculatedly cute Ryo-kun. And above all, his timing for pulling back is so unfair; the constant stream of "you can't say that and expect me not to be curious..." moments had my heart unable to keep up. Before sleep, he says, "I want you to dream of me," and the reason behind that is so lovely that Ryo-kun's deep feelings made my chest tighten. As I drifted off to sleep, listening to Ryo-kun's occasional sleep-talk made my heart race, and right at the very end, he drops a bombshell, leaving me thinking, "Um, um, please keep letting me hear this going forward...!" in a rather selfish way. I've become unable to sleep well without Ryo-kun's spell, so from now on I think I'll have him lull me to sleep every day. Once again, thank you so much for letting me encounter such a wonderful work that feels like it gently accompanies daily life. I hope it reaches as many people as possible!
