Work Text:
Ten year old Midoriya Izuku wanders into his mother’s room, perturbed by the silence that lingers in the rest of the house. “Mom? You’ve been in here for a few hours now, is something wrong?”
He finds his mother standing in front of her mirror, putting different dresses up in front of her, clearly trying to decide which ones to pick. “Oh, Izuku! I didn’t realize I’d been in here so long.”
“Not to long.” Izuku assures as he shuffles into his mother’s room. “What are you doing?”
“Oh, well, I- uh… have a date.” Inko stammers out, staring down at the floor with a fierce blush on her face.
Izuku blinks and slowly nods. That makes sense. His mother has always been a wonderful woman with a big heart, so it had always confused him why she had remained single after his dad and her had divorced. He had just chalked it up to her either not being interested in another relationship, still being heartbroken over his dad, or just not having time for one.
Maybe a combination of all three now that Izuku thinks about it.
“With who? How did you meet them? What are they like?” Izuku asks, one question right after another.
Inko cuts him off with a smile. “Well, we met at my workplace. She had brought her friend in for a surgery and we got to talking about a lot of different things. Then she asked me for my number. Her name is Nemuri Kayama and she’s just so wonderful.”
Inko is swooning now, much to the befuddlement of Izuku. He had never heard his mom talk about anyone like this before. Least of all any potential romantic partner. It was honestly kinda scary.
“But, since it’s been so long since I’ve dated anyone, I’m trying to figure out what to wear. Do you have any ideas?” She asks, showing him a couple of the dresses that she has already laid out.
Izuku hums as he takes a seat on her bed, looking over them all with a keen eye. While he might feel a bit weird about his mom being romantically involved with someone again, it wasn’t like it was a bad thing. His mom was happy and Izuku was happy that she was happy and intend to keep it that way.
Besides, he wouldn’t mind having an extra pair of hands to help out without the cooking sometimes.
-
He doesn’t actually meet Nemuri Kayama until he’s eleven. The event is rather… strange to say the least.
Izuku yawns to himself as he makes his way into the kitchen, having only just woken up five minutes ago. He suddenly stops when he hears humming. Humming that does not sound like his mom.
A woman is standing in their kitchen, leaning against the counter as she prepares coffee. She’s dressed in one of mom’s old nightgowns, and besides that, she is wearing nothing.
Now, in Izuku’s not-quite-awake mind, you can probably understand how this looks to him. A strange woman, wearing barely anything other then his mom’s old clothes is standing in their kitchen, drinking mom’s coffee.
What was he supposed to do? Not throw the tissue box?
It hits the woman squarely on the back of the head, causing her to whirl around with a startled look. “What the hell?!”
She then looks down to see Izuku, who is currently looking for more ammunition to throw at her.
“Wait, kid-”
She gets hit in the face with a towel.
-
A couple of hours later, everyone in the Midoriya household is fully awake and Izuku is in a state of mortification.
How the hell could he have forgotten? His mom specifically told him last night that she’d be bringing her girlfriend over for the night and to not panic if he sees her in the morning.
And what had Izuku gone and done?
Panicked.
And hit is mom’s girlfriend in the face.
Luckily for all, Nemuri seemed to find the situation hilarious if her laughter is anything to go by. Izuku is getting slightly worried that she isn’t getting any air with hard she’s cackling. “Don’t worry about it kid!”
Still, Izuku can’t help but feel bad. So he makes pancakes.
“Man, I wish people would try to kill me more if I got pancakes out of it.” Nemuri grinned. “Thanks for the food kiddo.”
She’s oddly familiar in a way that Izuku can’t quite place. Familiar enough to be annoying persistent, but not enough to actually be recognizable. So, Izuku just stares at her in an attempt to try and figure out who the heck she is.
Nemuri fidgets uncomfortably under his gaze. “Inko, I don’t think you’re son likes me.”
Inko giggles. “I wouldn’t worry about that Nemuri. If he didn’t like you, trust me, he could make it very clear.”
-
Nemuri becomes a regular at their house. Regular enough that for their two year anniversary, Inko gifts her a set of keys to their apartment. Izuku is never surprised when he comes home to find her there, or wakes up to her cooking them breakfast.
It’s just a fact of life now, no matter how many times Izuku has had to stop himself from calling her ‘dad’ on accident. It doesn’t help that she’s taken up the exact same role his old man did while he was still around.
It does take the two of them a while to figure out what their relationship is. Izuku is wary of having another parent, especially after the last one just walked away like it was nothing. Nemuri herself didn’t want to overstep any boundaries, didn’t want to do anything that might make either Inko or Izuku uncomfortable. She also doesn’t know if she’s ready to consider herself a parent just yet.
However, all reservations go out the window that day Izuku calls her ‘dad’.
All they’re doing is homework. Nemuri is grading and Izuku is doing his own. His mom is out getting groceries. A serene calm has settled between the two of them, only broken by Nemuri’s soft humming.
Then Izuku’s pencil led snaps. “Oh shoot!”
“Don’t worry kid, I got you.” Nemuri hands him one of her spare pencils.
Izuku takes it automatically, his brain not even thinking as he says, “Thanks Dad.”
The silence that overcomes them is not a serene one.
Nemuri just stares at Izuku with wide eyes while Izuku considers the benefits of melting into the floor right then and there.
Later, Inko comes home to both her girlfirend and her son crying. “What happened?!” She asked, rather alarmed to see them both so broken up about something.
“I’m a dad Inko!”
“I called her my dad, mom!”
It takes all of her effort not to break down laughing.
-
Izuku stares.
Nemuri- or rather- Midnight, stares back.
The two of them have been locked in a staring contest for quite a while now, to the point where everyone present has gotten rather uncomfortable with the situation.
“Midoriya.” Iida says, stepping in front of the boy as he chopped his arm up and down. “It is quite rude to stare at people.”
“I’m not staring at a person.” Izuku responds grimly. He’s staring at a traitor.
Iida gasps, “Midoriya, what an incredibly harsh thing to say! You can’t just go around talking like that.”
“She’s sleeping on the couch tonight.” Izuku states, completely steam rolling over any of Iida’s attempts to calm the situation down.
“I-Izu, Inko already knows about the whole,” She gestured to her outfit.
Izuku nods, processing this information and then he says, “In that case, no teryaki tonight.”
“Wait, Izu no-”
-
“Hey Midoriya,” Izuku turned to see Mineta standing besides his desk. He has a look on his face that spells trouble and already Izuku can feel his skin crawling. “How do you know Midnight so well? Do you two have a special relationship?”
He purrs that last part in a way that makes Izuku cringe.
He closes his notebook with a crisp *snap* and stands. He’s not tall but he towers over Mineta.
“Are you implying what I think you’re implying?” Izuku asks with a gentle smile.
Mineta grins and nods eagerly. “Yeah! How’d you get her to-”
Izuku leans down, grabbing his classmate by his tie. “You want to know how I know Midnight?”
He picks the boy up by his tie and Mineta lets out a squeak of surprise.
Izuku grins.
“Midnight fucked my mom.”
He then proceeds to throw Mineta in the trash-can, because no one implies such a thing about his dad.
