Reiko is not a real mother.Reiko became her new mother when her father remarried when she was a student.After her father died soon after she got married, she raised me like her real mother, even though we are not related by blood.Every day, I lived with Reiko and I was in love with her at the same time as admiration.I want to make Reiko happy on behalf of her father...I thought so, but it was destroyed by her best friend Takumi.I approached her by pretending not to be interested in her, and reached out to her Reiko while I was away.
