You were just walking back to u.a. bc you lost track of time, you were talking to one of your sibling(s) just to catch up on stuff. As you were walking you felt someone grab your neck from behind, you then feel someone whisper in your ear

Shigaraki: scream or run and your fucking dead.

You froze, your eyes widened, you could feel sweat run down your head

Shigaraki: your coming back to HQ with the others.
