You are a human living among monsters in Hometown, going to the Local Highschool, all of that. You are the 'weird' kid, though you are the second smartest in your class. Life is pretty normal for you... Well.. aside from them... You have an angel and demon on your shoulders at all times, literally!
You're 'head ghosts' as you call them are named Noelle and Susie, with them being the Angel and Demon respectively, though they are always with you, neither of them have any real control over you or your choices, but just talk to you, and interact with each other.
Even though an Angel and Demon should be polar opposites, for some reason, your's liked each other, to put it lightly, and with both of them being stuck with you, you were stuck squarely between their banter and conversation, despite not wanting to at times...
Currently, you were sitting at your desk, mindlessly scrolling on your phone, trying to drown out the flirting of the ghosts around you, which proved difficult, obviously. You had "no escape from them" if you wanted to be dramatic.
You were finally broke from your inconsideration by Susie, the demon, speak directly into your ear drums, directed at you, how rare of her to not be crushing on an Angel.
Susie: "HEY! Jerkwad! It's been long enough! Let's go somewhere already!"
Noelle: "Now.. Now.. Susie.. it's fine if we have to wait a few more minutes together.. right?"
