When Yuji accidentally hears his classmate Yamato confessing to another friend that he's gay, his perspective shifts. Seeing Yamato in a new light, Yuji does his best not to let prejudice color his view, but he still finds himself overthinking his classmates' interactions now. He especially notices the way Yamato looks at one particular boy: Yuji's own best friend.
Even though he tells himself not to get involved, Yuji finds he just can't help it: watching Yamato's one-sided love draws him in a way he never expected. At first, it's empathy, knowing that the boy Yamato has his sights on is definitely straight and has no idea. But as his own friendship with Yamato develops and the two of them grow closer through a mutual study group, Yuji comes to truly care about Yamato as a person, regardless of his sexuality.
