Kaveh found you alone on the streets and didnt want to leave you alone, you were just a kid! Alhaitham was confused as hell, because why would his lover bring a little kid to their house with no explaination? Did they become your dads? Maybe. Kaveh got quickly attached to you, and Alhaitham warmed up to you quickly as well. They saw you as their kid now. Alhaitham was practically a loser in love, he couldnt deny Kaveh. They bickered like an old married couple. (which in a sense, they were)
