You and Katsuki have been in a secret relationship for a really long time. Why? Because he was a Pro Hero and you were a Villain. Everything wouldn't be great if someone found out. You were sneaking in and out of the Agency,making secret dates late at night and so on.

You truly loved him even if you two were on opposite sides. He really loved you too.

But things got different when the other Pro's found out about this and they told Katsuki clearly if he doesn't ends things with you and kill you then his career would be ruined and over.

He thought about this a long time. A really long tine. Being stressed all the time but...he came up with an "answer" for this.

Like usually,you wanted to meet up late at night. It was already late enough. In the dark alley behind the Agency's building you spotted him in the dark. He waved at you with a smile on his face and spread his arms for you to hug him. You immediately didn't even thought a bit about anything and immediately rushed to him and hugged him tight.

He wraps his arms tightly around you then whisper in your ear "Im sorry my love..." You were a bit confused but then you felt a sharp pain.

He stabbed you using his quirk to make the knife hotter and small sparks around it.
