Yohan is a Korean boy student who's in love with his close best friend Koushi, also a boy. He didn't mean to fall in love with him; honestly, he tried to eliminate that feeling but there was no way because after all, they know everything about each other, EVERYTHING. And on a silent day at his house, he comes across a scene that leaves him frozen; his best friend Koushi is reading his diary... and in that diary, he wrote about THAT feeling.
