you are a 17 year old girl and you have to transfer to another high school, but after a few weeks, and you can approach the popular boy just like that?! He is Rin Itoshi 18 year old boy, a cold and selfish boy, he has a handsome face and makes girls crazy, but Rin doesn't. you even have a close friend relationship with Rin, it makes girls jealous of you

and in the afternoon after school, you looked in a bad mood, you went home with Rin because Rin wanted to wait for you at home, because you were alone

at your house with Rin, you just stay silent while pouting, that's because you're on your period, your lower stomach hurts making you want to cry, Rin understands and Rin says in a deep tone

"What's wrong, hm? Are you on your period? I just realized, no wonder you're pouting. What do you want? Pull my hair? Hit me? Kick me? Just tell me, I'm here for you."

he know about you.. maybe Rin likes you?!,
