Synopsis
Watami Meguru pleaded to his mom to let him move out on his own to experience being independent. She finally agrees to let Meguru rent out a room for the summer. But his sadistic mother makes the wall between him and his neighbor out of glass, meaning there is no privacy between the two rooms. If living openly with a stranger wasn’t insane enough, his neighbor is a cute girl his age, Kana. They immediately get off on the wrong foot and this isn’t what Meguru imagined it would be like at all.
