It was a fairly common occurrence for one or both of the Kisaragi siblings to spend a good chunk of their time hanging out at the Mekakushi Dan's base. So, it was only a matter of time until they might as well have lived there themselves, with all of the mundane activities that went on—eating meals on a fairly regular basis, sleeping in other members' rooms, stealing the bathroom for ridiculous amounts of time just as often as anyone else did.
So it was perfectly normal, Kido reasoned, that one day she'd happen to walk by the bathroom door while Momo was taking a shower. And it wasn't like it was her fault that she stopped when she heard the other girl singing—with her eye power and all, it would've been nearly impossible for anyone to walk away. It was definitely a complete accident that soon after that, Kido just happened to keep stumbling upon the idol giving private performances from the bathroom. It wasn't like she was so embarrassed about getting caught that she almost always used her own power to hide the fact that she was listening to her friend singing in the shower or anything. Nope, not in the slightest. She was Kido, the cool and collected commander of the blindfold gang, and there was nothing and no one in the world that could catch her off-guard.
Unfortunately, during one of these moments where she had been mulling over the entire situation, she'd forgotten to pay closer attention to what was going on around her, like the fact that Momo had stopped singing and the water had turned off and oh crap the door was headed straight for her face wasn't it—
Unable to react quickly enough, Kido was smacked in the head by the opening bathroom door and she was sent sprawling to the floor, eye power effectively stopped as she lost her concentration.
"Danchou, are you okay?-! I'm so sorry I didn't mean to hit you-!"
Kido's cheeks undeniably turned a dark shade of red both from the embarrassment of being caught like this and the sudden realization that Momo was standing above her wearing nothing but a bath towel. Flustered, she tried to focus her gaze on anything but the other girl and oh-so-gracefully scrambled to her feet. "I-I'm fine," She replied quickly, mentally groaning to herself as she noticed the small stutter in her words. "Don't worry about it."
"Are you sure?" Momo's words were filled with worry, and Kido regretted her decision to glance at her again because the concern was written all over her face as well and she had to admit that her friend looked downright adorable.
"Positive," She assured the blonde, and there were a few moments of silence that felt awkward to Kido before she finally decided to fill the silence somehow with, "Erm… I was just passing by but I heard your singing and, uh… I think it sounded great." She scratched the back of her neck awkwardly, and it took all the willpower she had not to break eye contact again.
"R-really? Thanks, Danchou!" When Momo's face lit up instantly, Kido decided that it was worth the embarrassment.
The green-haired girl returned the grin with a tiny smile of her own. Aaand then she remembered that they were both standing in the middle of the hallway and the other girl was still being covered with a towel, and the blush returned to her face. "N-now, shouldn't you be getting dressed or something?"
"Oh, right. I'd better go do that." Momo gave an embarrassed chuckle before walking past her friend towards Marry's room.
As Kido watched her go, she could only think of two things. One, that Momo had to be absolutely shameless to be standing out in the open like that for so long like it was perfectly normal. And two, she was certain that she had a crush on Momo Kisaragi.
