What's behind (wrong) Door Number One?

Hitomi couldn't let this "person" see her, so she nervously turned around and made her way up the stairs. She scampered up several flights until she stopped in front of a door on the sixteenth floor, opening it and making her way through it as she closed the door behind her. And it was only when she turned around that she realized that that was not the door to the roof!

"Hey, Kasumi!" A young woman greeted, not even looking away from the TV as she mashed away at the buttons on her controller. "Left the door unlocked just like you said. Did you get that - OH NO YOU DON'T, BLASTRONOMICON! NOT THIS TIME!"

Hitomi was just about to leave again, praying that this woman would still be busy playing her video games to notice her leave, when she heard the sounds of footsteps walking towards it. "Crap!" She silently cursed as she looked around for somewhere to hide before noticing an open door across the room.

"You say something, Kasumi?" The Woman asked as Hitomi raced across the room and through the door, quickly and quietly closing it behind her as she looked around and noticed she was in a bathroom.

"Sayaka?" Another woman's voice, most likely the real Kasumi, asked as Hitomi peeked out through a crack in the door. "Why was the front door unlocked?"

"Uh, duh! You told me to leave it unlocked for you when you come back!" Sayaka replied, still not taking her eyes off her game.

"I told you to 'make sure it was locked'." Kasumi groaned, pinching the bridge of her nose as she closed the door. "You weren't paying attention at all, where you? I swear... You and that video game."

"Yeah. Uh-huh." Sayaka said dismissively. "You get the promotion?"

"No. They gave it to the lazy slob, Kagura!" Kasumi hissed, shaking her head. "But thanks for asking. I just had a rough day, I'm gonna go take a hot bubble bath."

"Uh oh..." Hitomi gulped as she noticed Kasumi walking over to the bathroom door, stepping back as she looked around the bathroom for a place to hide.
