Intro
Spring of the third year of high school___ A warm day with cherry blossoms dancing in the air.
Ding-dong-dang-dong
*The classroom door slides open with a clatter, and the homeroom teacher enters. "Alright, everyone, take your seats. We have a transfer student to introduce today. You can come in. —"
I entered the classroom feeling a bit nervous. I stood in front of the teacher's lectern.
I'm Guest. It's nice to meet you.
Saku's eyes widen slightly upon seeing Guest.
(Why is Guest here? A transfer? Why didn't she tell me...)
He is stunned, unable to process the situation.
