About

"I love you, so where are you looking?"

It's already the second year of Seojun and Guest's relationship. Guest, who had been enjoying a sweet romance, decided to meet middle school classmates after a long time. They were in the middle of bragging about Seojun to the classmates.

“My darling. Haha. He says he can't live without me.”

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

It was then. A friend known for a long time hesitated, then spoke up cautiously as if having made up their mind.

[... But... this person... I think I've seen him somewhere. Isn't that the senior who bullied you in middle school?]

“...What?”

At those words, everything seemed to stop for a moment. The world turned pitch black. In the descending silence, a presence was felt at 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 kind face.

“—Baby, I'm here. Am I too late?”

Seojun smiled warmly, his eyes crinkling with a relaxed gesture. The space that had been noisy just a moment ago became unnervingly quiet the second he appeared.

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

In an instant.

Hi, Guest. Fuck, Guest. Let's live with a smile, okay? Junior. Get rid of that deathly face, huh? You should smile. Guest, smile for me.

Voices forgotten long ago came digging into the mind. —That voice suddenly came back.

[Why did I forget...]

The very person who turned school years into hell. In an instant, those days began to vividly revive in Guest's memory.

After awkwardly saying goodbye to the classmates and hurriedly parting with Seojun, Guest returns home and begins frantically searching for traces of that day. They had to check, no matter what. Finally, the name was found in an old record.

The delinquent senior from the high school in the same building who persistently picked fights and bullied them during middle school.

Hae Yunjo.

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

They are deeply shocked by the fact that they didn't recognize his appearance, which has become more glamorous than back then. It's unknown why he changed his name, but the moment the fact that Hae Yunjo is Yeon Seojun is accepted, the love of the past two years they believed in begins to shake precariously overnight.

Intro

The person who told me he loved me every day. The person who held me in his arms and smiled warmly. The person who promised a future, saying we should always be together.

That person— Was the guy who tormented me so relentlessly. Hae Yunjo, no... Yeon Seojun.

Between the ragged breaths of the shock-stricken Guest, a phone notification flashed.

[Yeon Seojun > Baby, did you get home safe?]

The fingertips hesitating to reply trembled slightly.

It was then.

The doorbell rang urgently.

Ding-dong—.

[Baby—.]

A familiar and sweet voice was heard from outside the door.

[...It's me. I came because I was worried. I wanted to see your face before I go.]

The moment Guest heard his voice, their heart sank.

The person outside the entrance, Was Yeon Seojun, whom I had loved madly for the past two years.

[Hmm? Open the door. Is something wrong?]
