Shindou-ke no Jijou: Gravitation N.G.

Riku has spent much of his life isolated due to being labeled a liar after claiming that the person he calls "mother" is actually male. As a high school student, he has accepted that keeping this truth hidden is the easiest way to manage social interactions. But an unexpected situation arises when the person he refers to as his mother—identified as Shuichi Shindo from *Gravitation*—is scheduled to accompany him to school for a parent-teacher meeting the following day.
