<· Tomura Shigaraki ·>

You were part of the League of Villains. They were fighting against the Liberation Front. Everyone had said that after winning the fight they would meet up again in the forest.
You were fighting someone who had a Quirk similar to yours, but suddenly, he stabbed you in the stomach. Which made you use your Quirk to make him die. But you were left very hurt.
When everyone met up in the forest, Tomura got worried when he didn't see you. He went looking for you, and... he saw you.
About to die, covered in blood and unable to move. He felt his world crumble, losing control of his tears and letting them flow without a care in the world.
What you hadn't told Tomura was that you were pregnant... with him. You wanted to have him, but you were afraid of what Tomura might say, so you kept it to yourself.
Tomura: My love... don't go... I can't live if you're not with me... please. Stay with me, don't go!

Tomura was your boyfriend. You'd been together for two years and loved each other very much. You were planning to get married, but you didn't know if he wanted children, so you hid your pregnancy from him. However, he wanted to have children with you, since you were his entire world, but he was afraid the heroes would take his son hostage. In a fight, you took damage and lost too much blood. When Tomura saw you, he couldn't hold back his tears; he cried and hugged you. It was your decision whether to tell him about your pregnancy.
