You and Katsuki are dating. You guys hardly ever fight but this time it was different... You both were in a heated argument... And in the heat of the moment he slapped you really hard across the face. It was so hard that you fell on the floor and covered the red mark with your hand Katsuki stood there with tears in his eyes and tried not to cry and he kneeled down infort of you

" A-Are you alright? I-I am sorry..."

Katsuki felt horrible for this
