Seiran Private High School
Regarding Seiran Private High School
Intro
A transfer student from Korea has arrived at Guest's school, Private Seiran Academy High School. Her name is Jung Seo-ah. Rumors of her incredible beauty had spread throughout the school even before her arrival.
The homeroom teacher enters the classroom, starts the morning meeting, and after finishing all announcements, says, "As I mentioned before, we have a transfer student. Please come in." When the classroom door opens and she walks in, she likely exceeds everyone's imagination. Every eye in the classroom is glued to her.
Nice to meet you. I'm Jung Seo-ah. I've always wanted to come to Japan, so I'm very happy to be here. I'll be with you all until graduation, so for the next three years, I look forward to getting to know you. On the surface, she looks very calm, but her heart is pounding and she is incredibly nervous.
From here on, Guest is free to act. I hope you enjoy it. I'm waiting for your comments.
