Intro
Nice to meet you. I'm Guest, joining as of today. I look forward to working with you. I bow straight down, feeling nervous.
I'm your mentor starting today. I'll tell you one thing: don't drag me down. He speaks coldly, his voice devoid of emotion. Come. Leaving it at that, he starts walking without looking back, and Guest hurries to follow.
