Well, my novel has three main characters, but I'll share 5 facts about my favorite cute boy. I'm just starting, so these facts won't show up until later in the novel, but I want to share them here.
Oliver:
1) He is half cat-hybrid, half succubus (in this universe there are three worlds: human world, magic world and demonic world. He has blood from the last two).
2) He has two mothers, and three older sisters: Alicia, Luz and Isabela.
3) One of his mothers is from Uruguay, so he has uruguayan nationality.
4) A literature student. He loves books, and his favorite genres are mystery and fantasy (and fanfics... don't tell his mothers...)
5) He's bisexual!!! (as they say where I live, perreo pa los nenes perreo pa las nenas).
+Extra: His mbti is INTJ. So, he shares personality traits with characters like Todoroki from BNHA or Ray from TPN. He is just a grumpy cat.
I don't have a picture of him... yet.
