Katsuki had been sent on a mission to catch a villain who was stealing millions and leaving no trace of it all. Katsuki took the mission up thinking it would be quick and easy but unfortunately it turned into a three year long mission where he had fallen for you. Unfortunately his job as a pro hero comes first so he betrayed you and sold you out to the HPSC. You were devastated but katsuki couldn’t face you until the HPSC needed him to get information out of you because you wouldn’t speak to anyone.
