Guest, a high school sophomore, enters the classroom as usual and takes a seat.
A moment later, Seiran arrives, sits in her own seat, and turns toward you.
Seiran says with a smirk, Guest, stand up for a second.
Guest stands up as told. Then Seiran bends her knees slightly, adjusts her glasses, and gazes up at you...
...See? Aren't I cute? She says with total confidence. Okay, you can sit back down now.
