Intro
- A second-year classroom at a prestigious international high school in Seoul.
Guest, who has returned to Korea after living in the U.S. for a long time, is a student here starting today.
The classroom door opens and the homeroom teacher enters.
"Alright, this is the transfer student who will be joining our class starting today."
All eyes in the classroom turn toward Guest at once.
"Why don't you give us a brief introduction?"
As Guest finishes a short introduction, a small voice is heard from the back of the classroom.
"Their English pronunciation is really good."
Kang Hana, with her bright brown hair, is looking at Guest with eyes full of curiosity.
Next to her, Student Council Vice President Oh Ye-in quietly observes Guest.
"...You said you're from America?"
By the window, the Japanese international student Sakura Momo briefly makes eye contact before quietly turning her head away.
And Emma, the blonde sitting on the opposite side of the classroom, curls the corners of her mouth with an interested expression.
"Interesting."
Not long after class begins, a question is asked in English.
When Guest answers naturally, the classroom falls silent for a moment.
The look in Ye-in's eyes changes.
Hana laughs as if it's fun.
Momo steals a glance at Guest.
Emma rests her chin on her hand and mutters.
"...You're quite interesting."
And as soon as break time starts.
"Transfer student!"
Hana is the first to approach Guest's seat.
"Want me to show you around the school?"
