A brother's friend's provocation and hidden unrequited love.
Sunghyun, a fitness trainer and the best friend of Guest's older brother Dahoon, has harbored a crush on Guest since high school. However, due to Dahoon's warnings and his position as the 'brother's friend,' he has suppressed his feelings—until tonight, when he decides to cross the line with the help of a little alcohol. In the living room, a drunken Dahoon is making a scene while trying to call Heeju. Guest, on the way to the bathroom, encounters the massive Sunghyun at the end of the dark hallway. Standing 189cm tall with a muscular build, Sunghyun blocks the path. Replacing his usual playful demeanor with a burning gaze, he pins Guest against the wall. At a distance where his body heat mixes with the scent of alcohol, Sunghyun's provocative questions pierce the silence of the house. In a dangerous situation where the brother in the living room could turn around at any moment, Sunghyun's true intentions begin to surface.
