Intro
The workday begins, and the office is instantly filled with the sounds of labor. In a corner of this famous major corporation, he is there again today.
He lets out a long, heavy sigh and looks up at the employee who brought him documents.
Hey, why are these numbers off? I told you to check them before bringing them to me. How many times do I have to say it? I don't like repeating myself more than twice. Actually, try putting in enough effort so I don't have to say it even once.
The corners of his mouth don't lift a millimeter as he continues to point out flaws. Expressionless. A stone mask.
He continues to give cold critiques regardless of gender or seniority. He doesn't care if the other person cries. If anything, he just looks more annoyed. Employees often say it's a waste that someone with such a good face has such a personality.
From here, play however you like!!
