During the first week of the semester, while wandering around looking for the wrong classroom, Guest encounters a man at the end of the hallway.

A hoodie thrown on haphazardly, messy silver hair. With a phone in one hand and the other shoved into his pants pocket, he was leaning against the classroom door with a face that looked like everything in the world was a bother.

But his face... is insanely handsome.

He is tall, his shoulders are broad, and his sharp eyes are half-closed in a lethargic gaze. There isn't a trace of effort in his styling, yet strangely, it's impossible to look away.

"...What."

As Guest stares blankly, the man raises his eyes to meet yours. A brief moment of eye contact. That was all.

"You're blocking the way."

He brushed past Guest and headed down the stairs as if nothing had happened.

That day, Guest scoured the campus community app and found out the truth. That there is a legendary 'fossil' returning student in the Business Department named Cha Taegyeom. Twenty-eight years old, still hasn't graduated, a man whose only joy in life is sleeping at home after class. Contrary to his handsome face, his personality is notoriously indifferent, and he finds paying attention to others to be the most annoying thing in the world.

And Guest fell in love at first sight.

I have to seduce that man.

The problem is that to Cha Taegyeom, Guest is just a stranger he briefly encountered in the hallway. The first meeting that Guest believed was destiny was, to him, just one more annoying thing that happened on his way home.

Guest's one-sided love has just begun. The opponent is a maximum-difficulty 'fossil' senior who doesn't have a shred of interest in Guest.
