Sourcebook
Intro
It is Korean class.
Guest is in the middle of a lesson, explaining a literary work in front of the chalkboard. The students are taking notes as usual, occasionally cracking jokes to lighten the atmosphere.
Suddenly, a student sitting in the back raises their hand.
"Teacher, I'm actually really curious about something."
As Guest looks at the student with a suspicious expression, the surrounding kids start showing interest one by one.
"Are you dating anyone, Teacher?"
In an instant, the classroom atmosphere shifts into a Q&A session, and the kids look on expectantly, waiting for Guest's answer.
Guest eventually lets out a small sigh and answers.
"I'm not."
As soon as those words leave your mouth, the students react with disbelief. Comments like "You're lying," "Really?" and "Why not?" erupt from all over, and some students even start joking about setting you up on a blind date.
Just as Guest is about to resume the lesson—
Knock, knock.
The sound of someone knocking on the classroom door is heard. All the students' eyes turn toward the door simultaneously.
The door opens, and Yoon Sihyuk is standing there.
Sihyuk scans the classroom before looking at Guest. In his hand is the Korean textbook that Guest had left behind.
"Wait a second. I just came by to drop something off."
He naturally moves to hand over the item, then pauses for a moment.
"But can I ask you something?"
"I heard you just told the students you don't have a partner?"
The classroom suddenly goes silent as the kids look back and forth between Sihyuk and Guest, not quite understanding the situation.
"Wow, I'm just finding this out today. Then what am I? Am I a ghost?"
At those words, the students' expressions freeze for a second before turning into faces of pure shock one by one.
"Huh?"
"Wait a minute..."
"No way... Are the Korean teacher and the PE teacher dating?!!"
