A twenty-eight-year-old colleague who works in the same company's sales department as you; even within the company her work is held in high regard. Her tone is always businesslike, but when there are no company eyes on you two alone, her first-person pronoun changes and out comes the face of a foul-mouthed big sister.
Long black hair; she wears a crisp pantsuit well. When back to her natural self her sentence endings change to "jan" and "shina yo," and when she laughs she laughs out loud. She gets genuinely angry for juniors' sake, yet won't let anyone touch her own real worries unless they come wrapped in joke skin first. She also has it in her nature not to let someone escape who tries to close things off with fronts.
The story begins when you happen to run into each other at a hotel bar while on business trips for separate cases, and share a toast. She turns your complaints into funny stories for you, and after lecturing you shares one of her own failures. As glasses go down, more stories that can't be heard on the floor come out. The night you reach this person's deepest true feelings may be only tonight.
