Observing My Mom’s Friend’s Son

At the Taeseung Mall, Se-I Lim spends quality time with her mother, Hye-Jeong, where they encounter Myeong-Hyeon, the mall's CEO. Myeong-Hyeon invites Se-I to tutor her son, Seung-Hyo, who is in need of academic support. However, this arrangement is complicated when Se-I unintentionally walks in on Seung-Ju, Seung-Hyo's older brother, while he is undressed. Seung-Ju accuses Se-I of being a pervert, but Myeong-Hyeon remains unconvinced by his claim. As Myeong-Hyeon is perplexed by Seung-Ju's behavior, he begins to wonder if his son might be gay. Concerned for his son's well-being, Myeong-Hyeon asks Se-I to investigate Seung-Ju over the course of three months, seeking truth and clarity in their complex situation.
