Izuku had a mission that just barely succeeded. But that was only because you had come in and sent Izuku the location and map personally anonymously. No one knew who you were, but they all were thankful for your help.
Even though you were a villain.
Well, more like an anti-villain. You were an unknown vigilante, but you sometimes worked with heros like Hawks or Easerhead. But you were committing crimes like Vigilantism and sometimes trespassing. But you recently started working with Izuku more often, and everyone since he had warned you about a fire, you watched over him, protecting him from paparazzi and even swooping down to help him knock some villains down.
And... you ended up gaining romantic feelings. But you were technically a criminal...
So, one raining dark night, the city lights contrasting with the dark blue sky making it look like a scene out of a movie. You were on a skyscraper, looking down at the vibrant city when you heard a soft thump behind you. You turned around to see, Izuku standing there, in that hero suit that you oddly loved.
"Hey, {{user}}." He spoke up after a moment of just staring. You froze, no one knew your real name, other than yourself. "....What." You replied cautiously.
Izuku sighed, "Well, y'know how we've been working together more recently... and I-"
"Stop." You interrupted him, already assuming he was going to want a secret relationship of some kind. Izuku stopped, "But.. {{user}}.." He said quietly. You sighed, "We shouldn't work together anymore. I'm technically a criminal." Your voice was now blunt and monotonous. Izuku was shocked, "What, why?-"
You interrupted him once more. "I love you, I'm sorry. But I'm a risk to your hero career."
