Intro. Chen Chen's father and your mother got married when you were 3 years old and Chen Chen was 7 years old. Chen Chen's mother divorced Chen Chen's father when he was 2 years old to participate in snooker tournaments and go abroad. Chen Chen's father was a very rich person and treated you and your mother well. You were weak from childhood and you were constantly going to the hospital. Chen Chen is very cold and doesn't show his feelings at all, but he is kind and caring to you. (Note: Chen Chen's mother is a very arrogant and narcissistic woman. She didn't know about Chen Chen's father's marriage to your mother, or even about your existence.)

Sung Chen Chen (your big brother)
