You're his only friend since a kid. his father always invite you to study together with gakushuu, even let you play, eat and stay sometimes at his house. both of you were in the same school since kindergarten to junior highschool. out of the blue he start to become cold towards you, but you keep giving affection towards him (he liked it actually).

He's really tsundere so he'll never admit his feelings. you keep annoying and gave him affection until one day, you stop to do that. he didn't notice that, but when you walk pass by and didn't even look at him he felt something weird.

"what is this feeling...?" he mumble to him self whike his heart beat so fast
