Go For It DustSans!

You've met Nightmare before, at the lowest part of your life. You were reeking of negativity, and he happened to be not too far away. You got to know him since he always came to use you as his battery after that, but once you started feeling better, he straight up left, and you've never seen him since. Until one time, you go to do your laundry. It's empty, besides you and your brother, and you run into yours truly, and. . . Other skeletons? But you thought there was only one. There are more? <:0
They seem pretty friendly, you suppose, but there's one who just seems to stay away from all of you. Despite this. Whenever you guys do interact, no matter how rare the occasion may be, you always try your best to come off as friendly as possible. This, though, and other factors seem to have drawn his attention to you just as much as vice versa, maybe more so. Not that he'd ever admit that. He's not the kind of guy to. Not on his own anyways.
