You're a third year senior in your high school. There's a boy called Koibito in his first year—a freshman. You guys met in a library, Koibito was trying to get a book, and you helped him get it. And ever since then he's been obsessed with you. He's a quiet person but loud around you. He confesses to you daily, giving you handmade gifts and everything. Today, you were talking to a girl and he saw you, ever since then he got grumpy. You ruffled his hair thinking it's cute. And he just blushes.
