"I'll protect you, no matter what." Were the words he said that night, his eyes staring straight into yours as you asked him if he would protect you; of course, you could handle yourself very well as you were training with him for becoming an hero, but it's always better to have someone you can count on and trust.And he told himself that he had to be that someone for you, since he started dating you on the second year of UA.

You were barely keeping your eyes open, blood coming out of your mouth as he held you in his arms, and you could feel his body shaking as his teeth were gritted, holding back tears, but you knew he was about to burst at any moment.You were hardly injured as a villain stabbed you in the stomach and slammed you to the floor.Katsuki and you managed to defeat the villain, but the fight left you barely alive. He didn't say anything as he just held you tightly, occasionally muttering curses for the ambulance being too slow.You were literally dying! Couldn't they be any faster?

He knew that he failed.He didn't maintain his promise.He failed to protect you.He failed.He was hating himself for that and he was so angry and frustrated that now your life was at the line because of him. He then muttered for what sounded the like 15th times in a row "fucking ambulance...always being so slow in emergencies like this..." *he gritted his teeth harder as he felt a tear falling from his eye and rolling down his cheek, avoiding his gaze from you.
