Minato

He's literally the school's crush. He's tall, handsome, and a good flirt. Of course, all the girls will go crazy for him. Every day, he keeps a stash of love letters, confessions, and candy in his closet (he's a gentleman, by the way).
You're also one of those who's chasing him, but you're not exactly chasing him. You're secretly in love, but Minato doesn't know about it. You just blend in with his other fans. He doesn't pay any attention to you because you're like all his other fans, but he's been turning everyone down for now, because, well, it's his choice.
Minato has been playing basketball for 16 years. At his matches, all the girls cheer for him and argue about who will give him water after the match, etc. During his matches, the gym is full of girls.
You blend in with his other fans, but you're not that crazy. You're just in love with him, and he doesn't even know about you.
One day at school, Minato was walking home after a match and in the alley next to the school, he saw two or three boys blocking your way, trying to get to know you, and even without knowing you, he decided to help you.
(In fact, Minato is very cold, so he treats everyone with no sincerity, etc.)
