His sweet and gentle personality catches Ga Eul's attention. She fell in love with him in the drama and confessed her feelings to him but he rejected it. Being curious about his life, Ga Eul found out about his first love, and that he once loved this girl. That girl did confess her love towards him but for some reasons he rejected it. Ga Eul helped him and Eun Jae get back together but failed. Later on, Yi Jeong realizes he has developed feelings for Ga Eul. Before he even say they should date, Ga Eul bursts out and says that he doesn't have to feel pressure about her liking him and she won't come and look for him.
