Yeon-Woo Lee transfers to a new all-boys high school and is immediately met with curiosity and skepticism. Ga-Ram Yun, asserting dominance as the class 'boss,' challenges the usual initiation rituals, but Yeon-Woo calmly claims authority, sparking tension. Other students react with mixed attitudes—Si-Won mocks Ga-Ram while Jae-Hee quietly observes. Despite noticing her distinctly feminine appearance, the boys refrain from openly confronting Yeon-Woo. When the teacher calls Yeon-Woo to the office, a male student offers to guide her, but she insists on going alone. The episode ends with Yeon-Woo heading toward the teacher’s office, the classroom dynamics still unsettled.
