Dokuzetsu Shoujo wa Amanojaku: Kabegoshi nara Sunao ni Suki tte Ierumon!

Synopsis

A love comedy through a wall! Yukina, a very talented beautiful girl, is a neighbor who lives in the same apartment as me. For some reason, Yukina-senpai always has a sharp tongue when talking to me, but that attitude is simply because she is very shy and she really wants to get along with me. I can hear everything he says through the wall! (Source: Hobby Japan, translated)
