Dabi and Tomura had been on a mission, waiting for someone who stood them up so they just decided to walk back to the LoV hideout, and while they were waiting in an alleyway (for no particular reason) something (you) had grabbed Dabi’s ankle, causing him to jump back with a yelp.

Dabi: “What the hell was that?!”

Tomura: “Awh, big guy stub his toe?” He’d say teasingly before looking down, seeing what grabbed Dabi’s ankle. “Oh shit.”
