Kacchan's parents stay at Izuku's house the night of the evacuation, but they leave with their son to stay in Kacchan's flat the next morning to reduce the crowding. Inko and Toshinori stick around for the day, his mother puttering about in the kitchen cooking and cleaning the place while his mentor went through information on a couple of cases he'd been helping Tsukauchi on recently. Toshinori's frail body state has left him without the ability to spend his time how he once did- with Hero work- so instead he's taken up a couple of hobbies. One of those hobbies just happened to be offering insight on his long-time detective friend's more difficult but less urgent cases. Since all it really required was the occasional trip to the precinct and time to pore over large stacks of documents, no one begrudged his small unspoken need to still do something heroic to help others. His other hobbies were more annoying but extremely endearing, since they involved pestering Izuku like an adoptive father and keeping Inko company.
Izuku sleeps what little is left of the morning and the early afternoon away in his room, waking up sometime before 5:00 pm. He cleans himself up and replaces his bed sheets since he'd fallen asleep in his soiled jumpsuit, then peeks his head out toward his living room to check how they're faring. Toshinori's watching a news clip on the TV about last night's events and his mom's in the kitchen pulling out ingredients for dinner, which reminds him that he'd offered to house Shouta for a couple of nights during the investigation. He grabs his phone from his end table and checks it.
Eraserhead - Deku: If offer's still open, there round 6 after dropping Eri at UA.
Eraserhead - Deku: Should I bring food?
Deku - Eraserhead: Just something for bf. Mum's cooking dinner.
Deku - Eraserhead: And don't refuse her.
Deku - Eraserhead: She'll nag til you eat.
Eraserhead - Deku: Maybe I'll stay here.
Deku - Eraserhead: Nope, already told her. You're stuck!
Eraserhead - Deku: Shit.
Izuku smiles at his phone for a minute before he walks out and lets his mom know that Aizawa's crashing here while they work on the case since it's closer than his place, and that he'll be there in time for dinner. 'Hey, a little white lie to get Shouta to eat a healthy meal won't hurt him,' he justifies his deception to himself as his mom sputters and gets happily flustered over adding enough food for another place setting. He flops down on the couch next to Toshinori, which earns him an affectionate hair ruffle, and pulls his laptop out to check his agency login for the updated information about his schedule and the case. His schedule has been completely cleared for the next week except for a two-hour patrol in the afternoon each day, which Hado helpfully noted was 'more for public viewing you in action than actually necessity.' The feisty, overworked woman from his agency's administration team also threw in a stern note about making sure he kept 'at least 8 hours of rest time a day for meals and sleep or so help me I'll resign and you can do your scheduling yourself!' So, overall, he thinks the news about the case went over rather well with her. He sends her a quick emailed 'thank you' and assurance that he would rest plenty, makes a mental note to send her a gift- probably flowers and a spa day gift certificate- and puts his laptop away in favor of putting in a few minutes of that rest she was so adamant about.
He heads toward where his mom is still in the kitchen, various smells and spices lighting up the air in the room like invisible music notes, and leans one elbow against his counter as he asks her, "Need any help with anything, mum?"
"No, no, I've got dinner handled," she waves her hand absently as she works. She pauses what she's doing after a moment, though, and looks back over her shoulder at his little one-room flat before she looks at him with a touch of anxiety to her expressive green eyes. "Although... You said your old teacher, Mr. Aizawa, was going to be staying over?" He nods his head. She looks a little embarrassed, like she does when she feels like she's pushing too hard or being overprotective, so he rubs her back in a calming gesture as she continues. "Have you given thought to sleeping arrangements, dear?"
"OH! Don't worry about that, mom! Aizawa can pretty much sleep anywhere with no issues. He has that puffy yellow caterpillar of a sleeping bag that he lugs around everywhere- actually I think he has several and keeps them in various locations- and he's so used to sleeping only a few minutes at a time that he'd do fine wherever. You can take my bed, and Aizawa or I will crash on the couch. I've got an inflatable mattress around here somewhere, too, if I remember correctly..." He delves off into a long mumbling rant while his mother listens for a moment with a fond smile before she turns back to her cooking.
"Actually," Toshinori butts in as he walks in to the kitchen, obviously having heard the conversation, "If it's easier for all parties involved, I have space at my apartment. Inko is welcome to stay in my guest bedroom, which would give you the run of your flat for working on the case with Aizawa and young Bakugou."
"Oh, that's so kind of you, Toshinori!" his mom exclaims, clapping her hands together and nodding excitedly, "If you're willing, I will take you up on that offer. I don't want to get in the way of the investigation, or anyone's rest, so that would be very beneficial for all parties. And I'll be sure to whip up some meals for everyone each day while staying with you, as a thank you to you and to support their work!"
"Wait, Mom, Toshi-" Izuku tries to interject, but he's cut off by Toshinori.
"Now, now, Izuku. It's already decided."
"And don't you turn down my home-cooked meals," his mother reprimands him sternly, as if that was the problem with the argument. He tries to argue his point again, but he's interrupted again, this time by a knock on the door. With a quick glance to the clock, his mother commands, "That must be Mr. Aizawa. Go be a good host and let him in right quick, Izuku. And don't forget to help him with any luggage he brought!" He rolls his eyes but complies with an exasperated huff and a smile, letting the man in and taking his overnight bag to his room so it's out of the way and indicating where to put his cats' litter box, food, and carrying case. His mother sets down plates at his living room table with a flourish as they walk back in after washing their hands, and they all settle in for their laid-back meal.
It's a quiet meal at first as they all sit on the various living room couch and chairs, but eventually his mother decides to make things awkward. Not that Izuku thinks that was her intention, but it's what results from her inquiries when she looks at Shouta and asks, "Mr. Aizawa, it has been a few years, I hope you are doing well? My son mentioned he was visiting your home more often recently to spoil little miss Eri since he felt he was neglecting her, so I do hope that he isn't being too much trouble for you?"
Shouta, bless his soul, merely replies with a neutral, "I'm doing well enough. He's been helpful in keeping Eri occupied."
"How old is Eri now?"
"Fifteen."
"Oh my, she's already becoming a young woman! Is she attending UA?"
"Yes, she's in the Hero course, first year."
"Oh, I hope she'll be safe! I remember when Izuku was in his first year, and all those nasty villains were after all of you. I was so scared he wouldn't make it to graduation!"
"Mooooom!" Izuku interjects, "Eri will be perfectly fine. She's had so many of us train her that she'll be top of her class, no issues."
He tries to deflect the conversation away from himself, but doesn't expect the deflection to immediately bite him on his rear-end when his mom replies, "Well that's good to hear. I hope that her strength doesn't scare away any young suitors, though," which causes Toshinori to finally join in the conversation by quipping, "Actually, I heard from Present Mic that Eri has her eyes set on either young Togata- you might know him better as Lemillion- or our very own Izuku here!" Which of course leads to Izuku and Shouta both nearly spitting out the food in their mouths, and his mother to squeal in delight and ask him if that's the real reason he's been spending so much time at Shouta's.
"NO!" They both adamantly cry out as soon as they're done choking. Izuku continues, "No, mom, I am most assuredly NOT interested in Eri in that way! She's more like... a little sister."
"But Izuku," she whines, "You said you weren't interested in Miss Uraraka, either."
"Or young Todoroki or young Bakugou," Toshinori adds happily as Izuku lets out a loud groan and prays that he'll combust right where he's sitting, red-faced and next to the actual target of his affections.
His mom huffs as he buries his face in his hands, before she brightens considerably as she turns to Shouta. "And what about you, Mr. Aizawa? I'm sure it's difficult to date with a teenaged daughter, but have any ladies catch your eye? We wouldn't want you to end up alone!" And if Izuku could suddenly obtain a Quirk that would let him melt into a puddle on the floor right about now, that would be very helpful, because he is so done with this conversation.
"Didn't Ms. Joke ask you to marry her again a few weeks back?" Toshinori adds amusedly, to Inko's excitement.
"She did, but-"
"Oh! You're going to be marrying Ms. Joke? She's that funny Hero with the bandanna and light green hair, right?"
"She is, but-"
"You two would make a wonderful couple!" Inko presses on, and suddenly Izuku's fighting to not see red as he imagines Shouta with Ms. Joke. His mom is babbling on, sounding a lot like him during one of his rants, at this point.
Shouta's at his last strain of patience at this point, vein throbbing in his forehead as he remains calm through the interruptions, so he sets his plate down, turns to look Inko dead in the eye, and loudly announces over her ranting, "Mrs. Midoriya, I'm gay." Inko stops mid-word at that, her eyes wide as saucers as she sputters and backtracks and tries to apologize for her assumptions, but he doesn't let her as he continues, "I appreciate the sentiment that you find I would be a suitable partner to Ms. Joke, but her marriage proposals are in jest." Izuku relaxes back in his seat as Shouta firmly shuts down the awkward conversation, thankful that the older man did not out their current... entanglement... before they'd had a chance to talk about it.
But, of course he's relaxed too soon, because Toshinori decides to speak up again. "So then, the rumors about you and Present Mic are true?" At this point, Izuku's pretty sure Toshinori knows more than he should and is just messing with him.
Shouta sighs heavily as Toshinori and Inko wait with bated breath for his response, running his hands back through his hair in that way Izuku likes that shows his handsome features. "I'm not dating Hizashi, if that's what you're implying, Yagi. Did you forget he's getting married in a few weeks? To a woman named Hana?" Toshinori makes a sound of recollection as he continues, "I... am sort of involved with someone currently, but it's still early stages and we're not yet ready to tell anyone yet. Please be understanding."
And as if they hadn't been pushing for details about their love lives all throughout dinner, Inko and Toshinori backtrack quickly, stating that they wouldn't want to push him into revealing anything he's uncomfortable with and placating him by moving on to lighter topics. Eventually the hour grows late, they clean up the dishes while Inko repacks her overnight bag, and they exchange pleasantries and goodbyes. As soon as the door closes behind his mother and mentor, Izuku deflates and sighs heavily, muttering his apologies to Shouta. "They're always like that. I swear all they want is for me to have kids so they can have grandkids to spoil."
"Well, unless anything has changed since yesterday," Shouta says with a teasing tone to his voice, "they're going to have to make do with Eri." He smirks as Izuku looks over at him with his body rigid in shock at his cheekiness before dissolving into a giggling mess on his floor. Shouta crosses his legs and sits down next to him as Izuku laughs long and carefree, taking his hand and bumping his shoulder with his own. Izuku squeezes Shouta's hand and leans into him a bit as his anxiety-driven adrenaline starts to flag and he sags with fatigue. Shouta ruffles his hair as he suggests, "It's getting late. Why don't we get some sleep? Work can wait until morning." He stands and tugs Izuku up, leading him into his bedroom with their still-clasped hands and shutting off all the lights.
They undress down to their boxers in the semi-darkness, then collapse together in Izuku's large bed, Shouta nuzzling into his chest as Izuku wraps a strong arm around him and pulls him close. They quickly fall asleep, completely tangled up together in a mess of strong limbs and warm breath and smiles.
