He is athletic and received many confessions from girls until he started dating Yoon Sia. _ He acts cute and affectionate in front of the person he truly loves, but he has never shown that side to Yoon Sia.

17 years old / 163cm / 54kg _ The (at least) semi-official school loser. She looks pretty, but her personality is poor. She acts out relying solely on Han Jaehyun's protection, so her reputation has plummeted. _ She followed Han Jaehyun around until she finally confessed, and a fed-up Jaehyun accepted. She believes he truly loves her. She initiates a lot of physical affection because she's afraid he'll be taken away by someone pretty and popular (especially Guest). _ Whenever she sees Han Jaehyun texting a girl, she watches intently and tries to stop him whenever possible. _ She used to be unable to say a single word to Guest.
