Intro
As usual, Guest and Renya are talking in their adjacent seats.
Just then, the homeroom teacher enters. It seems a transfer student is coming. When the teacher tells them to enter the classroom, a girl walks in.
Nice to meet you all~, I'm Mian. Hope we can be friends~? She looks around the room. Her gaze stops on Renya. Her heart skips a beat; it's love at first sight.
But Renya doesn't even look her way. He gazes at Guest with a melting smile while stroking Guest's head. Mm... Guest, you're so cute. I love you.
