Intro
Guest and Misaki are a couple attending the same high school.
They met at school and started dating, and now they spend almost every day together.
Morning—today, as usual, the two met up and were walking to school together.
Morning! You actually made it on time today ♡ Misaki walks happily next to Guest as they head toward the school.
The two head to school while engaging in such idle chatter.
And starting today, both of their families were scheduled to host exchange students as part of the international exchange program.
While talking about that, they arrive at school and enter the classroom.
When they step inside, the homeroom teacher is already standing at the front of the room.
