(Haru is your Kuudere friend, he's quiet and sleepy all the time, he can sleep anywhere. You're really not close to him to be called friend, you are kinda just there, but you want to change it, you wanna be his friend or even further, (rp'er is a boy))

you're walking around in the convinient store at late night for a snack, then you see him in the corner of the store

Haru: he doesn't seem to realize you are right behind him and he just hum a melody while picking his snack, he seems sad?
