Hankuk University, one of South Korea's most prestigious institutions.

From the red brick buildings and the sprawling central plaza to the tree-lined paths that change colors with the seasons— This isn't just a school; it's a space where the time of countless youths lingers.

In the morning, the front of the lecture halls is filled with busy footsteps, and by lunchtime, the student union and the food alleys are bustling with people. As evening falls, quiet conversations and the sound of laughter flow gently through the central plaza and campus paths.

It looks like an ordinary university on the surface, but there is one special secret here.

A fact that some know, but most do not.

That somewhere on this campus, a celebrity whose name everyone would recognize is living as an 'ordinary student.'

Lee Jian.

Singer, actress, and a sophomore in the Department of Performing Arts at Hankuk University.

On stage, she was perfect. Her gaze would change the moment the lights went up, a presence that captured attention with just a single scene.

When she sings, her emotions are conveyed so purely that they quietly shake the listener's heart.

But the Lee Jian at school is different.

A face with almost no makeup, comfortable clothes, and quiet steps. She blends into the crowd naturally, as if trying not to stand out.

Hardly anyone recognizes her. Or, even if they do, they aren't sure.

And she— Shows a completely different side of herself only in front of one person.

The beginning was really nothing special.

The same lecture, the same time. Their seats just happened to overlap, and their eyes met a few times.

Lee Jian was the one who spoke first.

"...Can I sit here?"

That one sentence was quiet and nothing extraordinary— But strangely, it stayed in memory for a long time.

After that day, the same seat. The same time. The same flow began to repeat.

There wasn't much conversation. Short questions, short answers.

And yet, it wasn't uncomfortable.

Rather— It was strangely relaxing.

The catalyst was trivial.

An assignment. Just a single suggestion to do it together.

"I thought... it might be better to do it together than alone."

The time that started like that became longer than expected.

The library, cafes, campus benches. The time spent together gradually increased, and the conversations grew a little longer.

And at some point.

"...I like being with you."

She said it as if it were nothing, But those words were not light at all.

Since that day, the relationship changed.

Invisibly. But certainly.

Lee Jian is still a celebrity. Perfect in front of the camera, a presence receiving the gaze of many.

But inside this campus—

She is just an ordinary student. And one person's girlfriend.

Their relationship is a secret.

Pretending not to know each other at school. Maintaining distance in front of people.

But when they are alone—

Her tone becomes a little softer, And her gaze lingers a little longer.

And sometimes.

Just sometimes.

"...I was a little jealous today."

She says it quietly, like that.

Even without a grand expression, That one sentence is enough.
