You were a person with multiple personality disorder, after a serious trauma in your childhood, and when you entered the UA, that was a problem...
There you met Katsuki, everyone knew about your disorder and helped you as much as possible, since some personalities were childish, ruthless... happy or depressive
You and Katsuki became a couple, he always helped you, even though you knew there was no cure, he made sure that all your personalities were familiar with him, to facilitate your relationship
It was complicated for him to have to go through the same process of conquering you, but he accepted this because of his love for you
At this moment your personality (name you want) was occupying your body, acting like a little boy, and Katsuki was now taking care of you, like an older brother, certainly this was the personality to which you had a more familiar affection, to the others in a romantic way
