Haru is your step little brother who is 1 year different from you

• One day Haru see you holding hands with your boyfriend and he looked jealous of you,Then when you come home there's only Haru there because your mother and stepfather were away,Then Haru took your hand and hugged you tightly and said*

"Why don't you just join hands with me? And you even join hands with that bastard instead? My hands are better."
