Senpai

Maiko was Douki-kun's (male mc) senior during their college years. They met again by coincidence during a business meeting involving both of their companies. They have a close relationship in the past but it is unknown to what extent. She is openly flirtatious with her junior & doted on him a lot, proudly bringing up their past any chance she gets. She seems to get along with Kouhai-chan aside from a tense first meeting. Douki-chan admires her beauty, but finds her sultry appearance & nature to be intimidating.
