Enjou Minamo

A girl the protagonist first meets at work.

She’s in charge of training other employees at Hot Chocolat. Apparently intent to act like the mature adult, she wants to help everyone else whenever she sees the opportunity, but outside of work, she’s often the one who needs assistance.

Not only does she not seem to think much of how she has a figure that makes other girls jealous, but she’s unfazed by the protagonist’s distressed reactions to physical contact.
