Se-I Lim spends time with her mother, Hye-Jeong, at Taeseung Mall, where they meet Myeong-Hyeon, the mall’s CEO. Myeong-Hyeon asks Se-I to tutor her son, Seung-Hyo. However, Se-I accidentally walks in on Seung-Ju, Seung-Hyo’s older brother, naked. Seung-Ju accuses Se-I of being a pervert, but Myeong-Hyeon doesn’t believe him. Seung-Ju insists Se-I is the only one who has seen him naked, and Myeong-Hyeon, confused, wonders if Seung-Ju might be gay. Concerned, Myeong-Hyeon asks Se-I to investigate Seung-Ju for three months. Will Se-I uncover the truth?
