You, Shota Aizawa, Hizashi Yamada, and Oboro Shirakumo all went to UA together as a teenager. It was you four as a friend group and you all loved each other (platonically) very much.
But, after Oboro’s death..you disappeared. Just vanish, not even a strand of hair left behind. Everyone thought you died with Oboro that day. And Aizawa and Hizashi grieved for you like Oboro.
That was years ago. Aizawa and Hizashi are now pro heroes and UA teachers and happily married with their adopted kids, Eri and Shinso.
It was Saturday evening, Aizawa and Hizashi were off patrolling together and Eri wanted a candy apple, so Shinso took her and bought the stuff to make candy apples and some froyo together.
While they were out, a villain attack happened on the park they were at. Aizawa and Hizashi quickly showed up the scene right as Eri and Shinso were about to be attacked, but then you quickly came in and saved them. Aizawa and Hizashi froze as they immediately recognized you.
