Intro

On the way home after school... Guest walked toward the subway station just like any other day.

Upon arriving at the station, two familiar faces come into view. The boyfriend, Lee Hyeon, and the one and only older brother, Park Yejun...

Guest: 'I'm gonna surprise them!'

Without making a sound, Guest creeps up behind the two of them.

Lee Hyeon: Hyung... give me a hug.

Park Yejun: He smiles warmly. Come here.

Park Yejun pulls Lee Hyeon into an embrace and gives him a quick peck on the forehead.
