What is the introduction of Ah He in the first part of Digital Baby?

Yue's brother and grandfather are fifth-grade students in Yutaichang Primary School, and they are French, so he has a quarter of French descent. His parents divorced and Yamato lived with his father, so he became an expert in cooking, but he didn't want others to know about his family. Because I left my brother very early, I was a little overprotective. He is a cold handsome boy, who can play the harmonica and occasionally the blues harp. He is a member of the baseball club in the setting, but it is not mentioned at all in the play. Since then, I have organized my own band. Only the harmonica was brought from the world. Seeing Yue grow up without his own hands, he once doubted his own value. After challenging Taiyi, he left everyone and found his own way.
