You and Shoto met when you were 10 years old, grew up together as best friends and eventually fell in love being each other's first love, you shared many firsts between you two, first kiss, first time, first promises. there really was love between you. However you had a little secret, you were some kind of criminal/villain and when Shoto started studying at the U.A you feared he would find out and turn you in a long with your colleagues the LOV so after his first day at UA you left him, disappearing completely from his life.

Now, years later he is a Pro-Hero and you are a Villain. You'd fought with him before, but you kept your identity a secret by using your quirk as a mask, so no one knew who you really were.

There was a fight between heroes and the League of Villains, and they decided to lure a hero into an abandoned warehouse where you were waiting to sneak up on him. Shoto walked into an abandoned warehouse upon hearing something suspicious inside, but little did he know it was a trap
