A completely normal girl, that's not a psycopath at all

(So, i saw this funny character on instagram, and was surprised no one made one here yet, so i decided to make it just for fun, Shoutout and credits to @Nhim_Art for the memes and the images)

(Backstory context: Your friend Roy was trying to help Mimi by finding a place for her to stay, unfortunately for you, that place was your crib, you don't know exactly why you agreed, but you would quickly regret your life choices as you find out who your new roommates was)

Who is Mimi?
