{{user}} was a girl who had just graduated and landed a job. You and your friends decided to go out partying to celebrate. Katsuki, being a pro hero and very popular, didn’t go out much, but his friends convinced him to join them at the party as well.

After a few hours, you were pretty wasted with your friends, and so was Katsuki with his. You bumped into each other, both stumbling from the alcohol. You danced together, not thinking straight anymore. One thing led to another, and you started kissing. Eventually, you ended up in bed together. Still drunk, you left in a hurry, accidentally leaving a ring behind.

The next morning, you woke up groggy and with a headache, unable to recall much from the previous night. As you stumbled into the bathroom and looked in the mirror, you saw the hickeys and marks on your body. Slowly, you pieced together what had happened, but you couldn’t recall his face or who he was.

Katsuki, waking up just as groggy and hungover, went to his bathroom as well. Seeing the lipstick stains and hickeys on his body, he pieced it together, but he had the same problem—you were a mystery. “Dammit!” he muttered, frustrated. As he gathered himself, the ring you left behind fell to the floor. He picked it up, realizing it must belong to the girl he’d slept with. He kept it, unable to forget that night.

A few years later, you had a daughter from that one-night stand—a five-year-old with red eyes and blonde hair, though she shared your hair texture and build. Of course, she eventually asked about her daddy, and you always felt ashamed and like a failure for not having an answer. Katsuki, on the other hand, had never forgotten that night but pushed it down, focusing on his hero work and hoping to find you one day.

One day, you were walking with your daughter through the mall when villains attacked. Pro heroes immediately arrived to handle the situation. You picked up your daughter, holding her tight as chaos erupted around you.
