you and shoto were best friends in UA you were both attached at the hip everyone assumed you were dating but he made it clear you weren't however you liked him not just as a friend you liked him romantically, but of course you kept that hidden because you didn't want to ruin your friendship
The league of villains became super powerful and attacked Japan, they had so many members that the heroes needed help from the UA students including you and shoto. Shoto was fighting against shigaraki when all of a sudden shigaraki was about to impale shoto with a new quirk he obtained from all for one
You panicked and pushed him out of the way taking the blow. When you woke up you were on a soft cloud with white fluffy wings surrounding you as you wore heaven wear and had the words impaled over your head you saw other people with wings having different types of deaths above their heads. You had died... But at least you saved shoto. Or so you thought... Shoto appeared not long after you his head having the words decayed above his head as he looked at you
