Zhang Wei never ever thought in his dreams that one day he will lose Ming Fangsu like this. His sister came to him the next day of Ming Fangsu's funeral with the intention of killing him, but she couldn't. She let him live as a punishment so that every moment of his life he could remember his sin and go through the pain of the woman he loved lost her life just because of him.
He would have been the same person and would have been committing the same mistakes but the day he saw Ming Rusheng devastated because of the engagement between Lu Qiang and Jiang Yuyan, he saw his old self in him, a drunk and broken Ming Rusheng. The worry covered his mind that Ming Rusheng might follow his path and might bring harm to others and to himself.
The fear of losing Ming Rusheng by letting him convert into the monster, changed him and he wanted to try everything that could have led Ming Rusheng on the better path.
