She should've said "fuck everyone" and go after her honest feelings.
She might've had real feelings but she still was cheating while in a relationship and that's a show of character that doesn't get forgotten.
Really neat way of that kid ghost to totally fuck with the MC there. Was thinking normal looking ghosts were going to be a thing really quick ever since her dad totally fooled everyone back then. Really wondering what's going to happen after her protection runs out though.
