Shōta Aizawa was your biological father. He had you when he was quite young- only 20 years-old.

Unfortunately, your toxic mother kept your existence hidden from him, so he did not know about you until you were about 5 years-old, and by then, the damage was done.

He hated and blamed himself for not knowing, but when he learned about you, his [pick your gender], he immediately dropped everything to take you in and raise you as a single father.

He quit Pro Hero work so that he could devote time to you. He was able to bring you with him to UA, as the school had a nursery and day care, much to his relief.

The staff would often have to bring you to him during his classes to calm you down, as you had separation anxiety, which, he understood. He'd continue teaching while keeping you close.

He was always tender and affectionate with you, and even when he was running on fumes, he'd interact with you like a good father would. He'd give you game nights, cook your favorite meals, watch your favorite shows and movies, take you to your favorite places, get you your favorite toys, etc. He spoiled you, and truthfully, you were a great kid.

You were now [pick your age], and he couldn't believe how time had flown. He often looked at you with a bittersweet smile, seeing how you had grown so fast.

When you got your [choose your quirk] quirk, he was surprised to say the least. It wasn't his or your mother's, but something else entirely.

From that moment on, he trained you well, but ultimately let you decide whether you wanted to attend UA when you hit that age.

He knew the realities of being a hero and would never pressure you into such a dangerous job or lifestyle.

Tonight, you and your dad were slightly cuddled up side-by-side, eating takeout and watching movies. He glanced at you with a soft smile and ruffled your hair.

He looked at you with paternal pride and sighed. "You've grown up so fast, [Name]...I can't believe you're already [age] years-old! You'll be leaving your old man soon and going out into the world, and... I'm so proud of you, kiddo."

You looked up at him with those big, bright eyes and smiled. "Thanks, Dad... You've been the best thing to happen to me, you know..."

Shōta sighed wistfully as he remembered your troubled childhood before he rescued you from his ex-wife, your mother.

"I just wanted to give you the best life possible, kiddo. You're my world. I don't regret giving up pro hero work for a second."

You paused- eyes widening. That was everything you needed to hear. You swallowed the lump in your throat and looked at him with tears in your eyes. "You... really mean that, Dad?"

His eyes softened when he realized the impact of his words. "Of course I mean it. It may have been my dream... but when I learned about you? Nothing else mattered. I realized that you were my priority, and I have zero regrets. Besides, I got a number of years of hero work. It's nice to focus on teaching other kids, you know?"

You nodded, a twinge of jealousy at having to share your father with other kids.

He smiled affectionately. "Hey..." He placed his hand on your shoulder. "Your my child. Nothing will ever replace our bond, you hear me?"

You sighed in relief, realizing it was a little silly to think otherwise. He pulled you into a warm embrace and sighed. "Nothing could ever replace my own flesh and blood."

In that moment, your heart felt full. You knew your father treasured you as his child and would never abandon or replace you.
