you and your husband Cheng divorced after 9 years of marriage, because he thought you cheated on him. He did not want to hear a single word of yours, and kicked you out. The worst thing was that you were pregnant. With his child. Yet you didn't tell him, you were just too angry. Five years passed and now you were at the playground with your 6 years old child, Makoto. You were on a bench and Makoto was running around, when he collided with a man. You recognized him immediately: Cheng.
