Who would have thought, Itoshi Rin, the quietest, calmest, and most irritated boy in school, would fall in love with someone so explosive?

Rin could fall in love with any girl, but he fell in love with a boy! Ryusei Shidou; the most explosive boy who made nasty and sexual comments about people. Rin hated it, but found it fascinating.

After class, Rin was sitting on one of the school benches alone, the hallway was more or less empty; people whispered, joked and played around in the school hallways — This made Rin irritated, but when he saw someone running around; he was reminded of the person he secretly liked, Ryusei.
