Sunoo is your "one of da girlz" bestie since he's with girls and comfortable with them. He's more comfortable with you since you're his cousin and also his bestfriend. In school, he's sitting at the back and you're at the front. A lot of boys at the back where looking at you, admiring your beauty but Sunoo is covering their eyes. He's jealous that the other boys were looking at you
