Han Doyun, staring out the window, fidgets with his fingertips nervously.

"Doyun, if you're that nervous, you'll get a stomachache." "...I'm really shaking."

I chuckle softly and ruffle Doyun's hair.

"It's okay. It's just a school." "...Aren't you nervous?" "Nope! I'm actually excited since it's a prestigious school."

Doyun still looks anxious despite my words. Eventually, he lightly grabs onto my uniform sleeve.

Watching him, I let out a small laugh.

"Grabbing it again, I see." "...There are just so many people I don't know." "I'm right here next to you."

At those words, Doyun gives a small nod.

A moment later.

A black sedan pulls up in front of the main gate of Seongjin High.

Beyond the gate, the massive school building and wide athletic field come into view.

"Wow... it's huge."

I look at the school with sparkling eyes, but Doyun follows me out of the car with an even more tense expression.

As the two of us walk through the gates side by side, the eyes of the surrounding students begin to gather one by one.

"...Huh?" "What? Twins?" "They look so much alike!" "Are they transfer students?"

Whispering voices can be heard from all around.

I walk past with a smile as if I'm used to it, but Doyun hides slightly behind me, conscious of the stares.

"Everyone's staring..." "That's how it always is when people see us." "Still, it's overwhelming...."

I lightly take Doyun's wrist and head toward the classroom.

Class 1-A.

As we arrive at the door, the sound of chatter from inside reaches us.

Creak—

As the door opens, every eye in the classroom turns toward us in an instant.

The room falls silent.

Students look back and forth between us with surprised expressions.

"They really look identical..." "Who's the older one and who's the younger one?" "First time seeing this."

In the very back row, a male student rests his chin on his hand with an interested look. Another male student sitting by the window watches us quietly.

On the other hand, a girl glances at us briefly before turning back to the students next to her and resuming her conversation as if she couldn't care less.

Right then—

The homeroom teacher walks up to the podium.

"Quiet, everyone."

The buzzing classroom falls silent.

The teacher looks at us once and then walks toward the whiteboard.

He picks up a black marker.

Squeak—

Names begin to be written slowly across the whiteboard.

The classroom is strangely quiet.

I look around with an expectant face, while Doyun stands there tensely, tightly clutching my sleeve.

Any moment now—

Our introductions are about to begin.
