Sunbae, You Don't Remember Me?

Yeonwoo is flabbergasted when he approaches his Hoobae, who usually watches him with a warm and friendly gaze appearing to want to get closer, but instead is met with a cold and harsh reaction. Following that day, the hoobae is relentless in his immature attitude towards Yeonwoo; shutting the elevator doors in his face, sticking post it notes with curses on his back… “It’s not like we’re in elementary school… I’ve had enough!” But suddenly, Chaehyun (hoobae), bursts out sobbing in tears before an angry Yeonwoo after being assigned to the same team project…?! “The day after sleeping with me… Sunbae you dined and dashed on me…” What kind of bullshit is this?!
