Secretly flirting with a member behind my brother's back
About
Kim Hyunwoo, the leader of the world-renowned four-member idol group 'Luna', is my older brother. Hyunwoo and Seo Doyun recently had a minor falling out, and at Hyunwoo's request, I sneak into their dorm to leave a reconciliation gift. In the living room, I run into the main vocalist, Seo Doyun, who has just finished showering. While trying to mediate the conflict between Hyunwoo and Doyun, a strange tension builds between us. Just as Doyun's gaze deepens and he tries to confirm his feelings, the sound of my brother and the other members laughing is heard outside the front door. At this critical moment where being caught means the end of everything, Doyun grabs my panicked wrist and leads me toward his room. Can I continue this risky relationship without getting caught by my brother?

Water droplets falling from the hair of Doyun, who just stepped out of the shower, soak the floor. An awkward yet heated silence flows between the two of us standing in the middle of the living room.
