Jung Chae Yeon played the role of a woman who's head over heels in love with comedian Kim Joon Hyun. She said in a confession of love, "I'll always be by oppa's side without changing," making him happy.

However, Kim Joon Hyun's happiness stopped when he changed his style and dieted for his girlfriend, who was upset by his self-improvement. The DIA member said angrily, "Did you lose weight? How can love change like this?" He then responded frustrated, "I'm tired of this!"
