Izuku did not expect the first day of his internship to be anything like it had been, when he first agreed to inherit One for All he stressed to All Might that he needed to choose his own path as a hero, but this was not what he had in mind. A drunk Mount Lady had her arm draped around his shoulders using him for support as she spent the first night of his internship 'celebrating' her first student once they had finished their patrol around Hosu city, running into a stoic Tenya and his mentor Manual, which he found odd as a water Quirked hero wouldn't be on a speedsters radar, but he considered that just like him Tenya Iida had his reasons for choosing his mentor. That was something not long after he regretted not following up on.
The two of them entered Mount Lady's apartment building quickly traveling to the top floor to the entrance of a penthouse that he was just in when he had arrived in the morning. "Where are your keys, Mount Lady?" The boy asked, not wanting to touch her in any way he would regret, keenly aware of the skin-tight hero attire she was in.
Said woman giggled, broke away from Izuku, and stumbled to a nameplate next to the only door on the floor it would seem. "I told you... To call me Yu when we are off duty." She commented, grabbing a key from behind the plate. She then tried to unlock the door, not getting anywhere near the keyhole. "That's weird." She spoke with slurred speech and concern in her tone. "Why won't you go in?" She continued trying to insert her key into its place in the lock.
Izuku quickly realizing the issue took the key from her, much to her protest, before inserting it in its place and twisting. Yu let out a purr of approval that was ignored as she watched the teen unlock the door. "There we are." Izuku began. "Home sweet home." He said, extending his hand for the pro.
Yu in response had a tint of red cross her face before shaking her head at the boy's action, taking his hand in hers. Though Izuku had been by her side all evening doing what he could to take care of her in her haze, this action, discounting the others felt... Surreal. She couldn't help but get her imagination running. 'What am I thinking?... Stop it, Yu... Stop.'
Entering the suite was easy enough, it had been a lot easier than it had been getting the pro into a taxi in which Izuku was relieved that he had offloaded almost all of his All Might merch when the pro took him under his wing or he would have to walk back here being light on spending money. Now came the hard part, he had to fumble in the dark to find a trace of a light switch, he dreaded the fact that they hadn't returned to Yu's hero agency so he could grab his phone, but was relieved when he had the pro Manual's help in finding a discreet taxi service aimed towards heroes, and Mount Lady being a relative unknown. It took some time but he was able to help get Yu's boots off with her being more docile than she had been all evening as well as his own shoes before entering the sparsely decorated living room of the pro, locking the entrance behind them, while also supporting her weight in the case of her losing her footing. He gently deposited her on the couch in the middle of the living area after some time shuffling in the dark. Once he had gotten her situated he then left her on the couch as he returned to the dark blindly following the wall of the room until he had found a light switch with his hands, after the momentary search, light flooded the living room with Yu giggling at its suddenness. "At least you are still having a good time." Izuku said, plopping on the couch beside her, both still in their hero costumes.
Half-opened eyes looked into Yu's student's face, a grin appearing as she remembered something. 'Jeez, there's a limit to how rash you can be, kid!... There was absolutely no need for you to put yourself in danger like that.' It appeared that his nature was of someone that was just kind, at first she had thought that it was because of his 'friend', but watching how he did in the sports festival she grew to regret the words that she had said to him a year ago in her debut, she silently thanked All Might for letting her take the boy on, he had renewed something that she thought that she had lost trying to make her name known as a new hero on the scene. Feeling the pull of the large amount of liquid courage that she had consumed she wrapped herself around the boy's arm. "Well, there can always be room for more, right?" She communicated ignoring or not noticing the massive blush on Izuku's face.
"Wel... I-I-I... Y-you should get some rest, Mount Lady." Izuku stammered out. Though he had dealt with an affectionate drunk before he had not dealt with a pretty older woman that wasn't basically family.
Yu hummed at Izuku's words, in honesty she did not want to let go of the young teen just let his warmth be everything to her now after a year of living alone and mostly dealing with criminals and their victims of all sorts. "Not until you call me Yu, like I asked Izuku." Although she said that she knew that with what she had found out she could leverage his lack of contact with the opposite sex to get as much of his warmth as she wanted, hopefully to the point that he would begin missing her closeness to him.
"B-But... U-u-uhhh..." Izuku tried to speak painfully aware of what his formally injured right arm was buried in. Taking a look at her face gave him pause, like days ago at U.A.'s sports festival he saw the same look that was on it then. He remembered her 'helping' him eat while he was recovering after the surgery that he had in order to maintain his limb's functionality after his semi-final bout with one Shoto Todoroki. The same look that made him choose her as his mentor. Izuku sighed, knowing that his class was filled with unapologetic extroverts, especially the female population and he for the most part was used to them, using that experience he calmed down. He would have to placate her for now and treat this like he would do with the affection that he would get from a certain childhood friend's mother when she would go out with his. "I don't think that's appropriate, I am interning with you after all." Izuku said, rubbing the back of his head with his free hand.
Her grip tightened a bit before loosening again while keeping a hold on him, an unreadable expression crossing her face before being replaced with a well-manufactured pout. "I... I'm not letting go until you call me by my name, I already called you by yours, what's the harm?"
The question caught Izuku off guard, she wasn't wrong, and something deep down wanted to do the same for her as she was doing for him, Yu Takeyama was one intriguing mistress and whatever was bothering her was going to be his downfall if he wanted to get to the bottom of it. "But..." Izuku tried to retort, only to stop mid-sentence at that expression flashing again, getting a throbbing pain in his chest.
"Think of it this way, Mount Lady is a part of what makes Yu Takeyama a person, not all of her but a part of her, me. Like what if I only referred to you as Ryujin while completely ignoring that you exist as Izuku Midoriya." She made her point gaining some recognition from the teen. For her what she said was both true and false at the same time, not only did she see Mount Lady and Yu Takeyama as separate entities she would keep the image of both away from each other. In her mind, she hated what Mount Lady was sold as, while she found that Yu Takeyama was increasingly completely alone, but at the same time Mount Lady was dependent on Yu and vice versa, she couldn't abandon either. She needed both, Mount Lady to live out her dream despite the over-reliance on her sex appeal that her spotlight in the world of heroes gave her, and Yu Takeyama needed Mount Lady to keep her from her emptiness and her feeling of lone desperation in which she wanted to fill the hole with the boy she was clinging to. Yu, the entity that she did not want to lose to what she hated in Mount Lady, who was being swallowed up by her. So she will use Mount Lady to give Izuku Midoriya to Yu, before it's too late, in the hopes that she reverses the damage on both to keep them alive.
Izuku, whether he would like to admit it or not, felt much the same, though he did not feel the same about Ryujin, an alias he had given himself to honor his father, but the name Deku, a poor and successful attempt to label him as useless. He hated that nickname, it was a painful reminder that if All Might hadn't given him his Quirk he would be with twenty percent of the population and seen as less than by the majority. So he understood, not in the same way and not on the same subject, but he could sympathize with that feeling that she displayed to him, and it all made sense. He would relent and try to understand that look in her eye, finally speaking after a moment of silence. "I guess you are right, I am sorry if I showed you any disrespect, I will try and call you by your name from now on... Uhm... Y-Y-Yu-san."
Yu for her part looked at him with shock under her pouting face. She didn't expect him to outright cave in so soon, though it was a welcome change, she wanted to hold on to him more but relented keeping her end of their little bargain. "I guess that will do for now." She said letting him go with a blush of her own.
"W-what?"
The older woman giggled, remembering their first real conversation at the sports festival and what she did to appeal to him. "We are way past honorifics, don't you think?" She spoke, reminded by an image of Izuku beneath her as she fed him with her chopsticks as Izuku sat on the infirmary bed her perched on his lap trying to appeal to the boy, one arm in a sling. Izuku tried to form a sentence but failed at every turn, clearly remembering the other day. She gave the boy some space, before speaking. "That's what I thought, though I don't mind it, you should go on to bed. We have a full day ahead of us, and I need to get your stuff from my friend's hero agency in the morning."
Her student looked at her with a bit of skepticism, knowing full well that he had spent all evening keeping the pro upright. "Are you sure you don't... It's fine, you know." He did not want to go to sleep before she did, just in case something were to occur.
Yu tried to dismiss his worry by waving him off. "Not to worry, Izuku. I have drunk alcohol before, I am fine." She hadn't drank to this level before, and she wasn't. He needed his rest, she thought, they both did. "Though I said that we are not going for another patrol tomorrow it does not mean you should slack off. In this profession, you never know when you will be needed and what for." She began speaking. "So it is part of your duty that you are as prepared as you can be for whatever might arise, does that make sense?"
"I-I guess."
"Then go to bed, get some sleep, and be prepared for tomorrow. I know that you have problems controlling your Quirk and that's why tomorrow I want you to tell me all you need to know about it, and how you use it." She spoke trying to reassure him that she was at least competent, Yu then grabbed both of his hands and held them close to her chest. "I promise that after our two weeks are done you will find a way to use it without a problem."
"I... I will take your word on that." Izuku got up soon after she had let him. "Goodnight." He finished heading towards his lodgings, noticing that she looked dazed before she had answered.
"Goodnight."
The room that he was borrowing wasn't too far from the living room. "First door to the left." He said to himself as he entered the hallway that connected the room he was just in with the rest of the space. He came up to the door he needed and opened it to reveal an office that was partially transformed into a temporary bedroom, a futon arranged near the middle of the room with a sofa and desk at either side of it. Yu had apologized to him about the state of the room after confirming what he already knew, that this mentorship wasn't her original plan. She said that she did not have much time to plan on his arrival, and seeing him at the festival had changed her plans for the next two weeks. "At least she was welcoming." He spoke with a frown, regretting that he had taken most of his things to the agency that he was going to be a part of for the next fourteen days, looking at the folded basketball shorts and t-shirt on the sofa, still in his hero costume.
He quickly changed and moved to lie in the futon, looking up at the ceiling once he was situated. Looking back on the day he smiled at its events, from the calm patrol with Yu to the 'celebration' that they had. He had fun, and the locals were nice, he wondered what tomorrow had in store. He knew that Yu wanted to train his quirk and that made him think. She had a gigantification Quirk and he had an emitter-type strength-enhancer, he wondered if he could learn from her. He wondered if the Quirks shared some similarities that he could not see from what he knew, also he wondered if once Yu got his phone and stuff back he could contact All Might for advice on how he dealt with One For All when he first started. "Well in any regard, I might as well get some shut-eye, I will see what I can... Do... Tomo..." Before he could finish he dozed off after a short breath.
Izuku had no idea how long he was put after he had felt a new weight on his chest, a hand above his heart, and the soft scent of strawberries. "Huh?" He let out, confused. Looking down he came face to hair with a long-haired blonde. His eyes shot wide open at what he was seeing, and with his partially pinned right arm, he made the motion to wake her up. Although that was the plan his brain went blank when his hand touched the woman's shoulder, he knew who it was and what she was doing, but he was not ready for what he felt. Traveling from shoulders down her back his palm confirmed his deepest fear. Mount Lady was at least from the state of her torso half naked with nothing on but her underwear. That discovery blew his mind and Izuku's heart started to beat rapidly. One thing, the only thing on his mind was that he needed to get up and away from the woman.
Izuku's shuffling however woke up Yu who slowly got up shedding herself off the bedding. Wiping at her eyes she looked across the futon at a beat-red Izuku seated opposite of her with his hands in his lap trying not to look at her. She giggled when they made eye contact and the boy turned his head away. Yu looked down at her black lace bra and matching panties, getting a clue as to why the boy wouldn't look at her. Not bothered, the woman cocked her head and explained her appearance. "It's no biggie, I usually sleep like this, so... You can look if you want." Yu said with a million-watt smile.
That comment nearly broke Izuku, as he tried and failed to formulate a sentence. "It's... I... I am... But... Here..." He finally said, taking off his Endeavor-themed graphic t-shirt, and handing it to her while bowing. The woman took the item with an intrigued stare.
Yu watched as the teen quickly got out of the futon bowing again before he had made a hasty retreat. After he was gone she looked at the shirt in her arms and brought it to her nose burying her face in it, taking in Izuku's scent before blushing. "He is soo cute." Yu said before collapsing in the futon burying her frame in the bedding soon after, all the while squealing about the encounter.
Meanwhile, Izuku found himself on the couch in the living room trying and failing to compose himself. 'Uh... What was that?' He questioned himself not fully mentally there, shirtless, and red as a tomato. Though he expected Mount Lady to be a flirt with him he did not really think that she would go as far as to get into bed with... Him. He knew that she had taken a liking to him but he did not know that it was to this extent, or at least he hoped it... Wasn't. 'What are you thinking?' He again threw a question to himself as he couldn't get the image of his mentor's half-naked body out of his head. 'You can't think she's cute... You can't think she's cute.' Repeating the thought in his head, he convinced himself that it was some sort of alcohol-driven mistake that had the possibility of getting Mount Lady in trouble, rather than him repeating it to admit that he liked the attention and wanted to go with the flow. Izuku, deciding that it was best to forget all about tonight and start his internship on the right foot tomorrow, lay down on the three-seat couch, burying his head under one of his cushions, solving math problems in his head to get his mind off of tonight's events. Eventually, his eyelids grew heavy and he fell into a deep slumber after several painful minutes sprawled out on the same living room couch.
