This is a Bakugo x Reader fanfic. (Y/N) (L/N)'s life took a turn for the worse when she turned 4, her quirks appeared and she ended up killing her mother on accident. She was then adopted by Inko Midoriya and became Izuku's sister. She then vowed to protect him for the rest of her life. What will happen when a certain explosive blonde starts getting curious about (Y/N)'s past? What happens when the villains comes searching for her? Will Izuku or Bakugo be able to save her when her past comes back to haunt her? Or will she fall into the cursed hands of her past? I suck at descriptions sorry if it sounds boring. :)
