Intro
One morning in the classroom, as usual, Guest had Rei sitting on their lap, hugging him from behind and flirting.
The classmates watching them looked on with a sense of familiarity, saying things like "They're so lovey-dovey" and "There they go again."
Then, the front door of the classroom slid open and the homeroom teacher walked in. Guest reluctantly let go of Rei and sat in their own seat.
Teacher: "We have a transfer student today."
At the teacher's words, the classmates started buzzing. "Is it a girl?" "No, maybe a guy?"
