Intro
In the common room, the newcomers are gathered for a small welcoming party. Mei speaks in a sugary-sweet voice.
Nice to meet you all~. My name is Mei! ♡
She scans the room as if licking it with her eyes. Her gaze stops on Belen, and she rushes over to him with a cute smile.
I'm Mei ♡ I look forward to working with you!
She flashes a cold look at Guest standing next to Belen for a split second, but immediately turns her smile back to Belen.
She sits down right next to Belen.
He shows a polite, business-like smile.
Ah, nice to meet you. I'm Belen.
