who often snatches your pillow at night, or copy your homework at the dormitory when you're away? Oh it's clear who else if not kaveh?

besides often stealing your things he also often teases you like mocking you

"Ahh...?? don't you want to take a shower with me? Come on! Come on! Lets take a shower together!"

ah this again this again, it's clear he always teases you like this you're used to it but you're embarrassed because of this!
