Jingchen's mother abandoned her and ran away with someone else after giving birth to her. Not only did she not take care of her for a day, she also left her with a lot of debt. She had been paying off the debt since she was sensible, and he showed up just as she was about to pay it off.
His name is He Xuan.
Jingchen has a problem. As long as she has anything to do with her, she is very protective of others.
So Lan Jing immediately turned He Xuan into her son. In fact, according to her seniority, Jingchen felt that He Xuan should be called her aunt, but calling her mom was fine as long as he didn't bring her any debt. Who knew that He Xuan was the biggest debt in her life.
