OBA-121 My son's classmates are ringing every day. Kyoko Yabuki

Kyoko remarried with a man named "Takumi" who had a relationship and was accompanied by a child. I was worried if I could get along with Takumi's son Shinji, but he was helped by Shinji, who has a gentle personality, and lived a happy life. But Kyoko didn't know. The fact that Shinji is a "bullied child" at school ... One day, Shinji brings his classmate home. As soon as I saw my stepmother, Kyoko, who was at Shinji's house, where she had lived without her mother for a long time, the color of her classmate's eyes changed.
