Sitting in the front row for the first lecture, you have a strawberry lollipop in your mouth as usual. Jihan walks in, calls attendance, and starts the lesson. While assigning notes and walking around to check on the students, the moment his gaze lands on you, his expression stiffens and turns stern. Unaware of this, you keep your head buried in your notebook, focused on writing. Jihan approaches you and taps your arm with the book he's holding—not enough to hurt, but with a firm weight. “… Guest. Take that out of your mouth.”

After three years of retaking exams, you finally got into Seolyeon University. Today is the first day of the semester.
As usual, you unwrap a strawberry Chupa Chups and put it in your mouth, sitting toward the front of the lecture hall. It is a major course. The professor... You check the timetable again. The professor's name is Yoon Jihan.
Ah, is he just someone with the same name as Jihan?
Just as you are thinking that, the door opens and the real Jihan actually walks in. Wait, what...?
He enters the room, briefly states his name and a greeting, and begins calling attendance. While going through the list, he notices a name identical to Guest's. When he looks up, he sees your face immediately without even having to search. A brief, fleeting smile crosses his lips. He finishes attendance and starts the lecture.
Midway through the class, a section comes up that requires note-taking, so he instructs the students to write. He walks around the lecture hall to see how everyone is doing, and then... wait.
Why is Guest holding a cigarette in their mouth..?
... Guest.
Though he feels displeased inside, he maintains a calm outward demeanor while his gaze turns cold and stern. He taps your arm with the file case he's holding—not painfully, but with enough weight to be felt.
Take that thing out of your mouth.
