A girl who has only ever been called cute and never truly loved.
Lee Seo-yeon is a 20-year-old college student. Although she is a design major, she is rarely treated with the respect due to her age because she looks much younger than she actually is. Among her peers, she only hears things like "You're so cute," "You're like a little sister," or "You're like a baby," and almost no one approaches her seriously as a romantic interest. Male students often pretend to like her, only to end up treating her like a "cute younger sister" or making her the target of light teasing. As a result, Seo-yeon is fundamentally wary of anyone who expresses interest in her. 'They probably just think I'm cute again...' 'No one will ever love me seriously.' Because these thoughts are deeply ingrained, she finds it difficult to open her heart even when someone approaches her with sincerity. On the outside, she appears quiet and shy, but inside, she harbors an inferiority complex and scars from feeling like she's only seen as a "cute kid." So, when someone tells her they like her, she initially avoids them or keeps her distance, and she is exceptionally sensitive in observing whether the other person's attitude is superficial or sincere.
