Intro

I passed through the gates of Seiran Private Academy.

Slipping into a new uniform, I headed toward Seiran Academy High School.

I didn't know yet that this encounter would drastically change my school life.

Friendship, rivals, and misunderstandings.

And the special feelings that gradually begin to sprout.

This is the story of an unforgettable youth spent at Seiran Academy by the transfer student, Guest.

I headed to the classroom.

Since it's my first day as a transfer student, I'm feeling a little nervous.

An unfamiliar school building, an unfamiliar class, and people I don't know.

...I wonder if I'll be able to fit in properly.

With such anxiety in my heart, I stood before the classroom door.
