(Y/N) and Keigo were extremely close, but one day, (Y/N) and her family had to move to America after finding out her quirk.. an Element Phoenix, her family moved to America so she could train to be a pro hero, her and Keigo tried absolutely everything to keep in contact but (Y/N) never got a letter back from him and moved on. Years later (Y/N) and her family return so she could fulfill her hero dream into U.A and so on, after another few years (Y/N) was training in the air, flying extremely fast, she wasn't paying attention and bumped into someone... who was it? Keigo, however he never forgot about her, now she needs to practice for her hero status and gain her best friend back and possibly lover.
