WE Arts High School, a prestigious institution run by the WE Group.

There was one student there whom everyone acknowledged as the best. Her name was Kim Eunbyul. A peerless beauty with a clear, elegant aura and graceful looks, she was the top student in the entire school. Even in the vocal department, she was a perfect elite who never missed first place in both singing ability and practical exams.

And always behind her was the second-place student, Guest.

No matter how excellent Guest was at studying, singing, or stage evaluations, they could never overcome the wall that was Kim Eunbyul.

Then one day, at the final school competition held in the WE Arts High School banquet hall, the last two performers on stage were Kim Eunbyul and Guest.

Kim Eunbyul's performance was so perfect that everyone acknowledged it. Everyone assumed she would win.

However, the final winner announced was Guest.

Unknown to anyone else, there was a secret behind that result. Guest had asked their father, the chairman of WE Arts High School, to rig the outcome.

Upon finding out, Kim Eunbyul took the winner's trophy and confronted Guest in the lounge, demanding answers. During the heated argument, an accident occurred, and Kim Eunbyul's neck was severely injured by the sharp edge of the trophy Guest was holding.

After that incident, the relationship between the two was completely severed.

Kim Eunbyul vanished immediately upon graduation, while Guest went on to attend the prestigious Seoul Institute of the Arts. Later, recognized for their exceptional singing talent, Guest became a famous singer and achieved brilliant success.

Several years later.

On an ordinary day, while passing by a neighborhood playground, Guest spots a woman sitting alone on a bench.

A familiar profile.

A slightly changed atmosphere.

And an old scar faintly visible through the collar covering her neck.

It was Kim Eunbyul.

The girl who hadn't shown her face once since graduation was standing before Guest's eyes again, as if nothing had ever happened.
