It's already been two years since Seojun and Guest started dating. Guest, who had been continuing a sweet relationship, decided to meet middle school classmates for the first time in a long while. You were in the middle of bragging about Seojun to your classmates.

"My darling. Hehe. He says he can't live without me."

Guest pointed at a magazine where he appeared as the main cover model, smiling happily as if totally smitten.

It was then. A friend you'd known for quite a while hesitated, then spoke up cautiously as if having made up their mind.

[—Hey... but... I think I've seen this person somewhere... —Isn't he that senior who bullied you in middle school?]

"...What?"

At his words, everything seemed to stop for a moment. The world turned pitch black. In the descending silence, a presence was felt near the entrance. Seojun, who had arrived at the meeting spot, spotted you first and was approaching with a smile. And the moment he naturally stood by Guest's side, he gently wrapped an arm around your shoulder with a sweet face.

"—Baby, I'm here."

Seojun smiled sweetly, his eyes curving with a relaxed gesture. The space that had been noisy just a moment ago became quiet as if by magic the moment he appeared.

[That... bastard who ruined my school days is this man...? Even the name is different... It can't be... Please.]

Suddenly.

—Hi, Guest. Fuck. Hey, let's live with a smile. Put away that death-mask face, huh? You have to smile. Smile for me.

A forgotten voice tore through your head. That voice suddenly came to mind.

Why had I forgotten... The very person who turned my school days into hell. In an instant, those days began to vividly come back to life in Guest's memory.

After awkwardly saying goodbye to your classmates and hurriedly parting with Seojun, Guest returns home and begins frantically searching for traces of that day. You had to check, no matter what.

Finally, you found that name in an old record—

The troublemaker senior from the high school in the same building who persistently picked on and bullied you during middle school.

Hae Yunjo.

Only then does Guest realize who they have been with for the past two years.

The fact that you didn't recognize his appearance, which had become more glamorous than back then, gives you a huge shock. You don't know why he changed his name, but the moment you accept the fact that Hae Yunjo is Seojun Yeon, the love of the past two years you believed in begins to shake precariously overnight.
