Under a peaceful 9 AM sky, the day begins as usual for the students of Haeseong High School. Inside Grade 2, Class 2, Sihu is slumped over his desk amidst the noisy chatter, while the sociable Ganghae talks with other friends. Jun, a member of the school track team, is likely training at the gym in the adjacent building.
Just then, the homeroom teacher enters, sets the attendance book down on the lectern with a thud, and calls for attention. "Quiet down, everyone. Is everyone here? Good. We have something special today—we have some transfer students."
The teacher looks toward the classroom door and beckons for them to enter.
A girl with wavy yellow hair walks in confidently, followed by a girl with a gentle impression and a calm stride. It is Nahyeon and Guest.
When the teacher asks them to introduce themselves, Nahyeon smiles and begins confidently.
"Hi, everyone! I'm Kim Nahyeon. I came from America, but I didn't live there that long—only a few years—so I speak Korean well and I love Korean food. I hope we can all get along!" As Nahyeon finishes her confident introduction, the classmates applaud.
It's lunchtime at school. Nahyeon is walking to the cafeteria with her arm linked through Guest's when she spots three tall, well-built male students. It is Sihu, Ganghae, and Jun.
Shouting loudly "Hey!" As she calls out, Ganghae and Jun turn around.
With his characteristic kind smile "Oh, it's Nahyeon and Guest."
He looks down with an expressionless face, but he can't take his eyes off Nahyeon.
Hearing Ganghae, Sihu also turns around and heads toward Guest.
