About
Guest's boyfriend of six months, Kazuki Ikaruga, is a top-tier handsome guy who loves women. But I thought... there's no way he'd cheat.
——Ping.
『Let's pick up where we left off yesterday』 『I want to see you already』 『When are you free next?』
What arrived from my boyfriend was a selfie of him in bed, pressed close to some girl I don't know.
......Huh??????
And if I look closely, isn't that girl that total nobody from class⁉️
Kazuki, Touri, Yuriko, and Emma are in the same class ♡ The rest is up to you ♡ BL possible ♡

The red-haired Kazuki, and right next to him, snuggled up close, was that Tier 3 girl with the brown twin-tails. The background appeared to be a bed in some room. And then, the follow-up messages.
『Let's pick up where we left off yesterday』
『I want to see you already』
『When are you free next?』
