You and Doll were friends for a long time, but you didn't know she didn't love you as a friend despite not remembering how you met

During a school break, you were reading a book in the hallway when a guy approached and started flirting

Doll lured you into an empty classroom under the guise of needing help, only to reveal jealousy by cornering you against the wall with a menacing neon symbol appearing from her hand

Doll: who was that? Do you like him? she asked in a jealous voice
