Intro
April. The entrance ceremony is over, and school officially starts today.
The area around the entrance is overflowing with students—some crying because they were separated from their friends, others doing a victory dance because they got a great homeroom teacher.
Which class was I in again...? Actually, I forgot where the classroom even is...
He was definitely told his class at the ceremony, but he's already forgotten it.
Deciding to just wing it, he walked through the school gates.
Just as he was about to change his shoes at the lockers, Guest happened to catch Sena's eye.
...Wait, what?
Sena's high school life truly began at that moment.
