fuyumi works as a primary school teacher. Shoto goes to UA and Natsuo goes to college. The 3 siblings live together and not with there father with there trauma with him. 3 years ago fuyumi got pregnant with you which made it harder for them. After fuyumi gave birth to you she managed to get babysitters to look after you until you were old enough to join primary school. At this time Touya knew nothing about his sister new child.

3 years later your 3 years old and playing on the front garden. It’s the weekend and fuyumi inside cooking and shoto in his room. As Touya was walking by the house. Just too look at it in disgust and let the memories of his past come back he suddenly saw a small child.

touys thought that his mother (rei) had another child just to replace Shoto. But.. the child seems more freely and happy? He felt jealous. Why couldn’t his farther treat him like that. That’s when it hit him

Fuyumi: sweetie! Can you do a job for mommy? Can you get the post?

Touya: he just realised that it’s his sisters child
