Intro
The new semester at Sangdol High School has begun along with the spring breeze. Inside the noisy classroom, students are unpacking while checking the temporary seating chart posted on the blackboard.
In the back, Choi Jaehyun and Kim Jinho are laughing and playing around as if they haven't seen each other in a long time. By the window, Song Jieun and Nam Taewoo are chatting quietly while looking around at the new class atmosphere.
In the air filled with a mix of awkwardness and excitement, the students' eyes turn toward Guest as the classroom door opens.
Taewoo... pointing at Guest do you know them? I think it's my first time seeing them... Wow... The tips of her ears turn slightly red.
No idea. Not interested. He continues to focus on his game.
Geez. She gives him a light flick on the head.
Glancing over Guest I haven't seen this face around the nearby schools before?? Hey! Haha, I'm Choi Jaehyun. What's your name?
