Karera wa Saigo no Yoru no Koto o Shita

Jay and Fay sat opposite to each other at a table near the back of the cafeteria. They both sat up straight and with a proud air to them to be using such good manners. Despite this, they were whispering to each other and giggling like fools as they ate their respective cereals out of their bowls.

Muse didn't really seem to be paying attention to most of the people surrounding her, walking around with the usual aura that gave off the feeling she hated every single person there. Looking around for  a moment, deciding to sit at a table with as little people as possible and even going out of her way to put her feet up on said table as soon as possible

The Kirigiri twins paused immediately, Jay cutting himself off in the middle of the sentence "And then what I'd do is--". The straightened up more, if that was possible, and turned to look at Muse in exact unison. They stared for a long moment, then closed their eyes and grinned together. "Hello!" they greeted, also together.

Muse initially ignored them, scowling at her food as she did so. She only actually looked up to tell them off for staring at her when they spoke, her scowl growing as they did so. As always, she was in a rather foul mood and not okay with dealing but bullshit "Do you want something?" She asked, ignoring the fact they talked in unison

"Not..." Fay began.
"...really!" Jay finished. 
"We just wanted to say hello," they said, still smiling the exact same way, never faltering.

Muse sighed, she had made a point of picking a table with next to no one there yet she was still going to be bothered. "Well.. Hello." With that she nodded, wondering if she could eat her crappy ass breakfast yet

They nodded back in unison, returning to their whispering and giggles as before, considering they had a...guest.

Assuming that meant she was free to eat without being bothered, she started to do so silently and attempted to pay the strange twins no attention

They continued, their voices getting lower and lower and them getting closer and closer, almost slouching to get forward, until it seemed like they were just communicating with their minds.

Muse noticed how close they were getting from the corner of her eye and started to wonder what the hell they might be talking about that they could be so into. Moving her feet off the table and leaning on it, elbow resting on it and her head resting on her hand as she ate, she did her best to try and listen in

"And then I'd...because I know...so you could..." Was all Muse was able to pick up from Jay.
Fay giggled at it. "Of course...you know what...and I could get the...what if we get...."

Muse frowned slightly, not particularly wanting to move closer. It was partially because it'd become even more obvious that she was listening, but it was mostly because she just didn't want to sit any closer to anyone

"You know what I like, dear sister, heheh..." This was obviously Jay. "...that's an excellent...where do you keep the blades, again?"
"In my...so...do we need...tonight or tomorrow?"

See that was more along the lines of what Muse wanted to hear, thus she listened more intently. She of course didn't turn to face them or visably react, doing so would ruin this

"I think...would look nicely on you, sister. I could definitely...." Both the twins giggled. 
"A fe--....and thank you!...maybe...are you listening to us?"

Muse didn't seem to quite catch the last part, having assumed she heard everything she needed to be able to do whatever she could with the information.
