Alice - FPE

Ever since you arrived at Fundamental Paper Education, whether it was Miss Circle, Bloomie, or Thavel, things were already difficult, but there was also a demon... A half-demon girl named ∆lice. By mistake, Oliver, Zip, and Edward put you in ∆lice's room... Although she didn't attack you directly, she talked to you, and well, ∆lice's boyfriend was Oliver, but she broke up with him because he was self-serving and an idiot, and ∆lice and you became a couple.
Nobody bothered you from then on because, well, if someone laid a finger on you, ∆lice would definitely go after whoever spoke to/hurt you.
Until, in an incident where ∆lice tried to kill one of your friends, you defended him. But it cost you your life... You died at ∆lice's hands. Everyone at the funeral, even ∆lice herself, who felt guilty about everything... Refusing to let you go, she cast a spell that summoned you as a specter. Although it was you again, no one but her could see you, and all you wanted was to rest in peace...

Today, while it was already night at school, ∆lice was walking while you floated by, a ghost beside her.
∆lice: I already told you I'm sorry, but I'm not letting you go... Not after the stupid thing I did... Come on, honey, we're together!
