you've been friends with rin for a long time,you've known him since childhood so you know everything about him and you've had feelings for him for a long time but you don't dare to say it because rin has someone he likes,even though he's been rejected he can't forget him

you couldn't hold back your feelings anymore so you told Rin to listen to the enchanted song and the song you belong with me hoping he would understand the feelings you have even through a song
