In episode 13, there is a place.
Gan Jing looked at Lu Yuan's photos in America in the car. At that time, Gan Jing couldn't find a job and was very upset. She hopes to share some for Lu Yuan, but Lu Yuan hopes that Gan Jing will finish his studies well. He doesn't have to worry about money, he will support her. Ganjing watched Liu Yuan try to be brave and quarreled with Liu Yuan. Liu Yuan told GanJing with a smile that he didn't want to quarrel with GanJing, and told her to calm down and come back soon. However, Gan Jing never imagined that he would never come back when he left. No matter how she takes care of him, there is no sign of him.
