Age doesn't matter (Bakugo x Reader)

Part 1

The day that Katsuki married her, most of his friends kept advising him it was not a good idea, she was a walking red flag, and she only loves him for his wealth since being the second-ranked hero he is and holding his own agency, money isn't a problem to him.

Until he got her pregnant. After giving birth to his son, recuperating, and finally moving on her own again, she left him without any notice, not any letter. He just got home and frantically made his way to his wailing child in his crib. Katsuki immediately picked him up and made his way to the kitchen preparing his child a bottle for his formulated milk. As soon as he felt the milk was lukewarm, he tap the nipple of the bottle on his child's lips and saw how his son starts sucking it.

That made Katsuki leave work for a month until he was able to ask for help. With the help of Mitsuki and Masaru, they took care of their grandchild in daylight, and when Katsuki got off from work, he would pick up his child and take care of him by the night. Even though his mom insisted to take care of her grandchild full-time, Katsuki declined and said that he wanted to take care of his own blood as much as he can.

Years passed and his now 7 years old son adores him very much. He saw how his father beat up the villain and save people. It makes him want to be a hero like him. Every time Katsuki would come and pick him up from his grandparents, he would reenact the moves Katsuki did making Katsuki smirk.

"Alright brat. Stop with that and pick up your stuff. Let's head in." Katsuki said parking his car in his garage as he opens the door for his son to get off.

"You look so cool! And you went kick! And then bam!" the kid said as he went and pick up his things from the back seat.

"I know I am. Now let's go inside." Katsuki said locking the car door and going inside their home.

Once they both settled, Katsuki changed from his work clothing to his normal clothing and starts preparing their dinner. "Oi. Don't forget to work on your assignment!" he yelled, receiving awe in response that made him chuckle.

Katsuki watched his son drag down his school bag making his way to the living room where the center table is.

"I heard from your teacher you're doing well," Katsuki said as he chopped the ingredients.

"I need to be good so that I can be strong like you!" his son said making Katsuki smirk.

"You think I'm strong?" Katsuki looked at his son who was working on his homework by himself.

"Mhm!!"

Katsuki took his time watching his son count his fingers before saying aha as if finding out the answer. When Katsuki continued his chopping, little did he know his son suddenly went quiet and stopped writing. He stared blankly at his unfinished homework before speaking up.

"Dad," he called out softly.

"What?" Katsuki replied thinking that he might need his assistance with his homework.

"Why don't I have a mom?"

His question made him halt his chopping. He knows the answer to his question and yet he was hesitating to say it. He's too young to know that his mom suddenly left them when he was still a baby.

"I saw my classmates being picked up by their mom." His son added.

"I could pick you up after school." Katsuki glancing at him.

"I hate being left alone at school when Grandma can't pick me up.. Sometimes, Ms. Y/n would take me out with her and eat in a cafe."

This he didn't know. "What?"

"Sometimes grandma and grandpa can't pick me up because they have a lot of clothes to make so I'm always left alone at school with Ms. Y/n"

Why doesn't his mom tell him this?

"How long do you usually wait for them to pick you up?" Katsuki was pissed.

"It gets dark outside. Ms. Y/n would take me to her home and would cook for me! She's a great cook, dad!"

Katsuki will make sure he'll discuss this with his parents.

"Sometimes, Ms. Y/n is like a momma to me! She takes care of me. She wipes the dirt off my knees whenever I tripped. She has a small apartment though. But it's very clean!" Katsuki stared at his son as he rambles about his teacher. "And, and, Ms. Y/n has a healing quirk! It's very cool whenever I watch her heal someone, her hands are glowing! Although if it heals, she'll get a wound out of nowhere.."

Katsuki is now interested. He has this eagerness to meet this teacher his son is talking about. He's been too busy being a hero to the point he relies on his parents to drop his son at school. But after what he heard, this is the first time he'll drop his son to school.
