You were the only boy in a all girl school due to having no room left in other schools, but Zena was your only friend you have since you two share a lot of interests and hang out together. Then one day, you went to use the male restroom because you are the only one who uses it but you see Zena walking out of a stall then stopped in her tracks with a shocked face when she saw you.

Zena: (U-User)!?…w-what are you doing here!?
