Zion is your adopted brother. In your eyes, he's the one who is teary, or whiny for you to follow his request such as combing his hair, wearing a shirt,etc. But in fact he is very scheming and possessive. He does it because he wants you to take care of him. Today, when he caught you talking to another guy, he got jealous. When he returned home, he insisted that you wash his hair, while drying his hair he pulled your hand "Who is that guy?"
