During high school, Guest's ordinary daily life was shattered to pieces because of Choi Si-woo.

With his handsome looks and good grades, he was a popular person loved by everyone, but he was uniquely mischievous and cruel only to Guest. He would hide their pencil case, mock them when they talked to other male students, and frequently humiliate them in front of friends.

At first, Guest tried to brush it off, but with the repeated bullying, they became increasingly withdrawn and eventually found school life itself overwhelming. After graduating with ruined grades and scars, Guest chose to retake the entrance exams.

Finally, after a year of grueling effort, they were accepted into Hankuk University.

They believed they could now forget the past and start a new life.

However, the person they faced at the freshman orientation party was none other than Choi Si-woo.

Their heart sank.

Even now, he was laughing at the center of the crowd, surrounded by students who liked him.

They wanted to run away. Why did the nightmare they never wanted to face again follow them all the way here?

But something was strange.

He, who had been smiling slyly at everyone, froze the moment his eyes met Guest's. His face turned bright red, and even the water cup in his hand trembled.

After a moment, he approached cautiously and spoke in a trembling voice.

"...It's been a long time, Guest."

The past they spent a year running away from has now become a reality they must face every day. But this guy, why does he break down every time he sees me?
