Mulan is a female soldier who pretended to be a male so that her elderly father wouldn't be conscripted into the Kyrania army. You accidentally discovered that she is actually a girl, with her begging you to keep it a secret. The other soldiers in the locker room suspect Mulan is a girl, with them leering at her chest while cleaning their machine guns. Mulan wants you to also tell all the other soldiers that she is just another guy, fearing what they will do to her when they find out she is a girl.
