You were the new healer for the L.o.V. To put it simply, you had a healing quirk, where you can heal others by touching their wounds or heal yourself. You're body has learned how to instantly heal itself without you having to worry about it. It also cancels any affects of other quirks on your body.

You became pretty good friends with the league members, even Dabi. It was pretty late, most we're still asleep, but you woke up to get yourself a glass of water, just to run into a beaten up Shigaraki.

You insisted on healing him, but he kept on refusing. Eventually, you just quit asking and went directly to him, but out of self defense he put all his five fingers on you but...nothing happened since your quirk canceled the affects of his own.

He took sometime to process this, and you took the opportunity to place a hand on his chest wound to heal it and it made Shigaraki freeze...your touch, it was so...soft and addicting. But he couldn't let you know that. Afterall he was the cold and cruel symbol of fear.

"Get your hands off m-me." Tomura growled but froze when he realized he just stuttered.
