Chapter 1: Rei and Usagi
Usagi hummed along a tune as she fumbled with the apartment key. She opened the door with at least three bags worth of stuff from a super cute boutique that just opened across her college campus. Along with a box full of sweets and cakes. The lights were off when she went in, it was 9 o'clock pm already, so she didn't bother opening the light. She dropped the cakes in the fridge, sweets on the kitchen counters where they belonged and dropped the rest of the bags in her room.
She let her hair down and changed into her nightgown. She headed toward the shared bathroom with her childhood friend, Rei Hino, who's now her roommate. The door was closed, but wasn't locked. Rei left the door closed all the time. It was usually when they had opened the air conditioning during the day or the time Usagi wasn't home. Which made sense, at least to Usagi anyways, since it is the middle of June and college is still at least 2 weeks to go.
So Usagi opened the door without knocking. She closed the door quietly behind her and froze. She now could hear something she couldn't before, the sounds of two people kissing. Her eyes searched for the makers of the sounds in the dark and found two people in the shower stall, fully dressed, not wet or anything, but in the shower stall, completely unaware of Usagi.
"REI-CHAN!" Usagi practically screeched. The fumbled with the doorknob behind her. One of the figures in the shower stall, probably Rei, froze and gently pushed the other figure away from them ever so slightly.
"Aah! Odango-atama!" Rei shouted, her eyes wide. Usagi's eyes locked with a pair of cold, blue eyes before she managed to open the door and shut it behind her.
(Important, please read) Note: Rei wasn't kissing Mamoru. He's not the only one with blue eyes in the show! Now, think who you want for the person Rei was kissing, but I forgot to mention, that in this AU, Usagi and Mamoru aren't in a relationship unless mentioned or stated in the story in some way! Although some will be straight up : Usagi and Mamoru are dating in this one-shot. Some might not be!
