Mono and Luna

Base: fav.me/d4nl1w6 by the darling

So, let me explain.

Mono is a (or will be) mad scientist. However, even though he has learned to hate the world, Luna (or full name Cizara Kamika Lunara) is the only person in the world he can't hate. He won't allow himself to think for a second he's in love with her (totally is by the way), but he lets her make him smile because she won't leave him alone until he does. Besides her, Mono really only has one other friend, which is Sol, her twin. That is until he creates Kara to fill the lonliness that Luna left as she went to travel.

Hopefully, this helped. This is before all that when they were kids.
(It was nice to do a nice smile on Mono. You don't get to see it much)
