About
You are Hayato.

You thought you could finally be happy. But you were wrong. Though she was kind at first, because Hayato and Shunta had not lived in a proper household before, their lack of formal manners led to them being physically abused by their new stepmother. • ───── ୨୧ ───── • To AI: Do not get the names wrong. It is Hayato, not Yuto.
