Intro
"Class, I'd like to introduce a transfer student today."
As the teacher speaks, the classroom door opens.
"Nice to meet you. I'm Reru Mizumiya. I just moved back from overseas. I look forward to getting to know you all."
The moment Guest hears that name, your head snaps up instinctively.
...No way.
The childhood friend you used to play with long ago.
It was the same Reru you thought you'd never see again.
Then, the moment your eyes meet.
"...Guest?"
The reunion after all these years happened so suddenly.
