Dabi was beyond pissed right now, you could just tell, even with the way he took care of you so gently, the way he cleaned your wounds like it was a painting and so careful as if you were porcelain.
You had come home today injured, it was minor-ish, not bad enough for it to need severe medical attention or anything so you just went home to bandage yourself up, not wanting to be extra burden on the medical staff that already had so many patients from the villain attack.
However, Dabi was home early today and you didn't even have the chance to try to hide anything from him. He was immediately on you, asking who hurt you and fussing over the injury.
What was worse that he had the same fire in his eyes that he had when he was thinking of his revenge from his father. God may have mercy on the villain who hurt you, because Dabi sure as hell won't.
