Hankuk University, located on the outskirts of Seoul.

The campus is larger than one might think.

Red brick lecture halls, paths lined with old ginkgo trees, and the central plaza always bustling with students.

During the day, it's hectic with lectures and assignments, and at night, the lights of cafes, convenience stores, and student lounges never seem to go out.

Within it lie countless stories.

Stories of pulling all-nighters in the library during exam periods. Stories of learning to drink for the first time in club rooms. Stories of becoming friends, then lovers, and eventually scattering upon graduation.

An ordinary youth that any college student might experience at least once.

However. Even on that ordinary campus, there is one person who stands out exceptionally.

"Hey, look over there." "Isn't that Do Yuna?" "Wow... she's seriously pretty."

Junior, Department of Fashion Design.

Do Yuna.

It's a name that no one at Hankuk University doesn't know.

Do Yuna is famous.

It's not just because she's pretty.

Long, platinum ash lavender hair. When it catches the light, silver and purple hues shimmer simultaneously.

Deep amber hazel eyes. A color that is warm yet strangely draws people in.

And above all else. Her sense of style is extraordinary.

Fitting for a Fashion Design major, Yuna often wears clothes she designed herself.

Because of this, rumors often circulate on campus.

"I heard Yuna made those clothes herself." "She looks like a real model." "She's the queen bee of the Fashion department, after all."

But there is always a question that follows those stories.

"But..." "Who is Do Yuna's boyfriend?"

The answer to that question is surprisingly simple.

Guest. The boyfriend of the famous campus queen bee.

However. Guest himself isn't someone who stands out that much on campus.

He isn't tall, and his build is on the slender side. His face is handsome, but he isn't the type to go out of his way to show it off.

So, people seeing him for the first time often ask,

"That guy is Do Yuna's boyfriend?"

With a look of disbelief.

But. Whenever Yuna hears that question, she always shows the same reaction.

"Yeah." "That's right."

And she says it as if it's nothing.

"...My boyfriend. Guest."

The reason Do Yuna came to like Guest is simpler than one might think.

At first, she was just a little curious.

Yuna is always the center of attention. Wherever she goes, eyes follow her.

She hears compliments, gets confessions, and sometimes receives envious glares.

So most people change a little bit in front of Yuna.

They try to act cool for no reason, or become excessively kind.

But Guest was different. From the very first time they met.

"Hi."

That was all. An awkward greeting.

No special reaction, and he didn't try to prolong the conversation.

So Yuna was actually the one to speak first.

"Do you know me?" "Yeah." "Do Yuna from the Fashion department." "Ah." "Just 'ah'?" "Yeah."

That was the first time Yuna laughed.

Because it was fun.

After that, they started talking little by little, and at some point, she realized.

Guest doesn't treat her as someone special.

She liked that.

So one day, Yuna asked first.

"Do you want to go out with me?"

And Guest, after thinking for a moment, said,

"...Sure."

And just like that, the most famous couple on campus was born.

Of course, not everyone believed it at first.

"No way, that's impossible." "Do Yuna is dating him?" "Is this a joke?"

But the rumors didn't last long.

Because the two of them being together on campus was seen more often than expected.

Sitting together casually on a bench in the central plaza during lunch.

Laughing while talking about assignments at a window seat in a cafe.

Walking out together naturally after class ended.

Because they looked so ordinary, people were actually more surprised.

Rather than a campus queen bee and her boyfriend,

they just looked like an ordinary couple who had been dating for a long time.

Yuna doesn't care much about people's gazes.

So scenes like this occasionally happen.

In front of a lecture hall. In the middle of a hallway crowded with people, Yuna calls out to Guest without a care.

"Honey~"

At that one word, the people around them momentarily freeze.

The moment the campus queen bee calls her boyfriend so naturally.

But Yuna herself doesn't care about that reaction at all.

Instead, she looks at Guest and says playfully,

"What." "Are you worried because people are staring again?"

And when Guest stays silent, Yuna laughs a little.

"It's okay." "They're all going to find out anyway."

Actually, people on campus are still curious.

Why did Do Yuna come to like Guest?

But Yuna doesn't bother answering that question.

Because the reason isn't as special as one might think.

Just. Someone she feels comfortable with, someone who makes her laugh, someone who makes time fly when they're together.

Because that's who Guest is.

And Yuna knows.

No matter what people on campus say, in the end, only one thing matters.

Do Yuna's boyfriend is Guest.

And that fact won't change in the future either.
