Perfect for listeners who love slow-burn step-sibling romance paired with immersive, gentle ear-cleaning ASMR.
On your very first hot spring trip together, your step-sister — a little cheeky and terrible at being honest — gives you an ear cleaning in your shared room. As the night goes on, she slowly lets her guarded feelings show. A gentle, blush-inducing first-love story captured in full binaural sound.
"I mean, sure, we're step-siblings and all, but isn't this kind of embarrassing?" "It's not like when I used to sleep next to you, Onii-chan. I'm not a kid anymore!" "That's exactly why—stop patting my head like I'm some kid! Geez, I'm gonna get mad, okay?" "Ugh, seriously, why did Mom and everyone decide to put me and Onii-chan in the same room..." "Onii-chan looks like he's feeling good, huh? Maybe I really am becoming an ear-cleaning master?" "Heh, maybe this is some hidden talent of mine. Ow! ..." "What? Don't just smack my leg out of nowhere! It's fine, so what if I get a little full of myself..." "Besides, I wouldn't clean your ears like this if I didn't like you." "What about you, Onii-chan? Do you like me too? ...Yeah, hehe... same here." "Ugh, this is kind of embarrassing... um, what should I do now. Um, oh, that's right..."
A cheeky step-sister who's bad at being honest about her feelings. Ending up sharing a room with her older step-brother, she resists being treated like a child, but as she gives him an ear-cleaning, she gradually starts to show her more genuine, tender side.

It had been a while since I'd encountered the "stepsister" trope, but Mei-chan, voiced by Yuuko Natsuyoshi, was just wonderful, so wonderful... There's a sense of distance where you feel that even a stepsister is still family. And yet Mei-chan appeals to her brother as a girl in her own right. The way the work expresses these two sides through vocal volume and distance really made my heart race as I listened. I think this is a strange, unique feeling you can't get from a friend or a lover. The distance between them gradually closes through ear cleaning. Please do watch it through to the end. Recommended for anyone who just wants to keep taking in the concept of a "stepsister" and the character voiced by Yuuko Natsuyoshi.
It's half a step away from blood relations that aren't actually connected by blood. Just think of the title's "a bit cheeky" and "bad at being spoiled" as decorations. She never hides her affection the whole time, so why...? And of course, I do my share of stupid teasing moves too (though it's basically negligible). Well, once you accept it, tonight becomes the fun course, so I guess it can't be helped? Also, I recognize this way of closing the distance. It's the same thing they do with "sensei" in Academy City! Isn't the humidity in this room kind of high? Ma~o......
First, I love how there's this indescribable sense of distance with the stepsister, and how her prickly side comes out. Even though in her heart she wants to say things a certain way, her bad-at-being-spoiled side shows and she ends up acting a bit tough, but then little by little she conveys her true feelings—I really love that kind of situation (*´ω`*) She's my favorite type of voice actress, and it also felt like a first-time kind of experience for me, so I decided to write this review.
