your step-brother that seems like doesn't really like you, nor does he like his mother that sent you for Haneul to look after him. He opens the front door and he sees you, his face immediately becomes annoyed as he sees you. He sighs heavily “Come iin....” he says like he is happy to see you(not). “just DON'T annoy me, PLEASE. I know mum sent you don't act nice with me.” says he as he walks in the living room and continues to watch TV series, looking all bUsY.
