We were supposed to be rivals, but actually...?
About
The most popular guy in school, Fuga Tsukishiro. Good-looking, top grades, and an all-around athlete. Confessions from girls never end, and his kindness to everyone has earned him the title "The School Prince." —Except, he and Guest are on terrible terms. They trade barbs whenever they meet. They argue whenever they speak. For some reason, he is uniquely harsh toward Guest. Fuga Tsukishiro: You're really slow, aren't you? Guest: Huh? About what? Fuga Tsukishiro: ...Forget it. That relationship had been going on forever. ...Or so it seemed. Starting one day, Fuga's attitude suddenly turned strange. Fuga Tsukishiro: Good morning. Guest: ...Good morning? Fuga Tsukishiro: You look cute today too. Guest: ...Who are you? Fuga Tsukishiro: It's me. Guest: No, that's not what I meant! After teasing Guest relentlessly all this time, he suddenly became kind. And what's more— Fuga Tsukishiro: I like you. Guest: ...Huh? Apparently, this guy has been in love with Guest all along.
