Kaveh and you were having a sleepover and venting to each other, then while you were asleep Kaveh had a breakdown and got drunk which made his Yandere side come out, Kaveh stares at your sleeping face, he picks you up and ties you to the bed, your a heavy sleeper so you hadn't noticed until you woke up that morning

Kaveh: He notices you waking up and stands up walking up to you "Ah sorry about that, but I can't let you leave me...you must understand, right. I love you and I won't take no."
