If you didn't know, Umbree is one of my main OCs, I made her about 2-3 years ago, and she's basically like a pink Underswap temmie... but is a cannibal, and has emotions, also is a demon without the power to reset, just knows of resets and is immune to them due to her coming from a different dimension. (She's also anthropomorphic-)

Marie, is my persona. I made her about a year ago when I felt like I needed a character to represent me, at first I didn't draw her much, but now I draw her more now that I'm experimenting with different poses, and to me she has a simple design, she has hair over her right eye because I used to not be able to draw a character without messed up eyes. Yep that's the only reason, and it stuck, it makes drawing Marie a lot easier. 

So-

Why would they get together?

Isn't this kind of a parent x kid relationship?
