Love of a Lifetime (Mirio x Reader)

"How are babies made?"

~~ time skip brought to you by BOUNTY~~

5 years later I know that a big time skip but whatever. You are currently 23 years old

You and Mirio are roommates. You two are Eri's guardian. It was gonna be Aizawa until you two volunteered. Aizawa thought you two were responsible enough to take care of her. So you both signed the adoption papers. Eri is 11 years old. Mirio got his quirk back and is the number 3 hero behind Hawks and you are number 4 hero.

Now that you're all caught up let's go to what's going on now.

Y/n POV

Mirio is taking us out to dinner tonight. He said to dress fancy. I put on a red long dress that has a slit.

Here are some options but you don't have to wear this outfit if you don't want to. Feel free to change it.

I gave Eri a cute red dress to match with me.

I tied her hair into a bun with a red ribbon.

Y/n: You look so cute!

Eri: Thanks m-mom.

I could cry right now! She called me mom. MOM!

I picked her up and spun her around. When I sat her down I went running to Mirio.

I started shaking him back and fourth.

Y/n: Guess what!!

Mirio: What is it?

Y/n: Eri just called me mom!

Mirio: She did?

Y/n: YES!

You started to do a little happy dance while Mirio just laughed.

Mirio: It seems like you haven't changed since high school.

Y/n: That is where you are wrong. I don't glitch as often.

Mirio: But you still do it.

Y/n: It's a work in progress.

Mirio: Are you ready?

Y/n: Yea!

The three of you left the house and got into Mirio's car. He drove you to this fancy restaurant. When you got in you ordered and you all ate. Afterward you all left to the park.

It wasn't cold out so you guys looked at the stars.

Mirio: I love y/n. I also love you Eri.

Eri: I love you too dad.

You look at Mirio and you could've sworn you saw tears in his eyes but he blinked them away.

Y/n: I love you both.

Mirio: I want to spend the rest of my life with you. And be a happy family.

He pulled a ring out of his pocket.

Mirio: Y/n M/n ( middle name) l/n, will you marry me.

Your eyes widened.

Y/n: Yes!

He put the ring on you finger and kissed you passionately. You heard Eri whisper something.

Eri: Gross.

You just laughed and brought her into a hug.

Y/n: I'm so Excited!!! We should start planning our wedding!!!

Mirio laughed at how excited you were. You all went home. As you were walking to your shared bedroom with Mirio Eri asked a question you didn't think she would ever ask.

Eri: How are babies made?

You looked at Mirio and he looked at you. Both of you had a shocked face. You thought she already knew. You never had the talk with your parents because you heard other kids talk about it at school so you knew. She 11 years old for gosh sakes how can she not know.

Mirio: Well you see when a man and a woman love each other very much.......

You guys explained to her how babies were made. She had a disgusted look on her face. Unknown to you or Mirio, Eri actually wanted a little sibling. She thought she could be a great role model but now that she know how babies are made she doesn't want her parent figures to have a child other than herself. The thought disgusted her.

After that awkward situation you took a shower and went to bed while Mirio and Eri watched tv together.
