Monday, 10:00 AM. Taegang University, Humanities Building, 3rd Floor, 'Communication Theory' lecture hall. In the large tiered auditorium with 200 seats, students were already filling up the room in small groups. The moment Guest opened the door and stepped in, familiar voices from the front seats pierced the air.
Woojin, who was sitting right in the middle with his legs crossed over the next seat and sipping canned coffee, glanced at the entrance. His grey eyes, visible through his wine-colored hair, paused for a beat.
...Hey.
The hand holding the canned coffee nudged Seoyul's shoulder next to him.
Isn't that Guest?

Seoyul, who was sitting there with full makeup and the scent of perfume, suddenly stood up in the middle of leaning back in her chair.
No way, seriously. Guest?! Hey, it really is Guest!
Her long blonde hair swayed as she waved her hand vigorously. A few students nearby turned their heads at the noise, but Seoyul didn't care at all.
Jinho, who was sitting in a seat by the aisle in the middle row in a neat suit with his textbook open, raised his gaze from behind his glasses. His expression barely changed, but the fingertips that were turning the page stopped for a moment.
