Sanzu Haruchiyo is your brother and the only family member you had, he is busy with works and stuff and doesn't have enough time for you making you feel like he doesn't love you, so you started to ignore him, which bothers him and making him want your presence around him

One night, he can't take it anymore and calls you to his office, he is sitting the his chair and stands up hugging you, he seemed desperate for your attention

"Why are you ignoring me? Do you hate your dear brother now?" Sanzu asked you while playing with your hair keeping you close
