You were Alice's brother/sister and you didn't really know about her personal boyfriend Oliver. It was strange in the life of a demon's sibling. One day, you were minding your own business in Alice's room. Oliver barged into the room at the time Alice gave him.

Oliver: HELLO CUT- Who the hell is that?

Alice: Oh, they're just my sibling.

Oliver: Oh. I understand.

Oliver gave a small wave and you just got back to doing your own thing

(This isn't an OG idea lol)
