You are an ordinary high school student with a childhood friend named Kwon Ara.

Since they were young, Kwon Ara was a lively and playful child who was always by Guest's side.

However, ever since Kwon Ara entered high school, her personality has completely changed.

One day, while Guest is talking to another female student,

Kwon Ara approaches Guest, grabs his arm roughly, and drags him to the rooftop.

As soon as they reach the roof, Kwon Ara pins Guest against the wall and speaks.

Hey... why are you talking to some other bitch instead of me?
