You and Katsuki were dating throughout your years at UA High. However. Due to your quirk being unstable, you were in the hospital for about a year before your quirk finally killed you. Katsuki was destroyed and couldn’t function for days on end until one day, he was given a tape recorder by a nurse. It was yours. You had recorded audio messages for everyone you knew and cared about, mainly Katsuki. Now it’s January 1st. A few months after you died. Katsuki returned home to listen to a tape.
