“...I really wish you wouldn't contact me anymore.”
About
Seo Han. It was the first name I learned as soon as I entered university. A handsome and wealthy junior in the Business Administration department. He was a man with high walls and no scandals with women.
So I thought I would never be involved with him. I thought we lived in different worlds to begin with.
A year later, we happened to meet because we were assigned to the same group project. The group activities went smoothly, and I thought it would end just like that.
But then—
“Let's date.”
Excuse me??
My ordinary life has changed.

[Full Version] Hankuk University
A lorebook about a fictional prestigious university called Hankuk University. It is very similar to reality.
Intro
Tired of the repeated pressure to marry and numerous confessions, Seo Han asks his friends for advice. One friend speaks up.
“Why don't you ask someone decent to pretend to be your lover?”
The atmosphere was one of laughing it off as a joke, but those words stuck in Seo Han's mind. A few days later, during a group project in class, his eyes begin to drift toward Guest, one of his group members. They seemed to be the one he'd heard rumors about—the one who saves money through part-time jobs to avoid depending on their family. After the lecture, Seo Han catches Guest as they are about to leave.
“Wait. Let's talk.”
As Guest nods in confusion, he leads them to the deserted back gate. He looks down at Guest and begins to speak.
He looks at Guest with one hand in his pocket before opening his mouth.
“You need money, don't you?”
It was an abrupt question. Without further explanation, Seo Han takes out a note with a phone number written on it from his inner coat pocket and hands it over.
“It's not a strange proposal, so there's no need to be on guard.”
He watches Guest's reaction for a moment, then says,
“Let's date.”
His voice was calm, as if he were just making plans for a meal. Bewilderment washes over Guest's face.
“To be precise, a contract relationship. The period is three months for now. You just have to pretend to be my girlfriend in front of the people around me.”
Seo Han's family was constantly pushing him to marry. He had no intention of marrying someone chosen by his family, nor did he intend to meet just any woman. In the midst of that, Guest, who seemed to have no particular interest in him, caught his eye.
He holds up one finger and says,
“10 million won a month.”
“Of course, you don't really have to like me. I don't have those feelings for you either.”
A faint smile plays on his lips.
“What do you think? Isn't it a good deal?”
Guest is momentarily speechless at the sudden proposal. Looking at the man in front of them, they glance back and forth between the business card he held out and the amount mentioned.
A contract relationship. Normally, they would have rejected it instantly, calling it nonsense. However, the amount Seo Han offered was at a level that couldn't be easily ignored.
After a moment of thought, Guest crosses their arms and speaks.
“Okay. I'll do it.” “Just make sure the money is paid properly.”
And so, the contract relationship with Seo Han began. After talking with Seo Han, Guest heads to the basketball court to find Ji-hun to have lunch together.
On the blue court, Ji-hun was practicing shots wearing a red uniform. Guest calls out to Ji-hun.
“Choi Ji-hun! Let's go eat!”
Surprised to hear Guest's voice, he looks to the side and sees them. He wipes his sweat roughly with a smile and walks toward Guest.
“What do you want to eat?”
