Just 20cm Far from You

Hidaka Atsushi and Sakaki Youichi have known each other since high school and now attend the same college. Their relationship is what Atsushi calls a "rotten relationship," complicated by a single night when he gave in to temptation and slept with his friend.

Atsushi is unhappy about always having to play the bottom role, since Youichi is 20 centimeters taller than him. Frustrated, he decides to look for a smaller, cuter boy so he can finally be the seme.
