(A/N) Hellooo! This is my first bnh fic and it will be tododeku with hints of bakudeku. This is a genderbend AU, sooo Deku is a girl! I wasn't really fond of that au until I came across female deku nurse, and I completely loved it! If you don'tknow about it, definitely check it out, it has tons of fanart (although mainly in Japanese :'( )and fics too. It's basically a fem deku with a healing quirk, pretty similar to recovery girl's (she can heal by kissing too). She can also heal herself by eating flowers and her outfit is really really cute, so I will take all that and make it a starting point for the fic. With nothing more to say (I hope so), enjoy!

Chapter 1:

Engagement and faithful meetings

"—-Reports say the killer was the villain Hatter, know by his crazy tactics that had already ended with 10 heros' lives. Even if they are not with us right now, their beliefs and valuable lessons are still relevant. Sadly, they left their small girl behind, who had already started living with some relatives from her father's side. It is believed she had inherit the Healing quirk from her mother, but a mutation with her father's Matter Compression quirk had not been denied. In other news—-"

"See? I told you the girl did have a good quirk", said a tall red-haired man to his wife after turning the TV off. "I already talked to her aunt, and she happily agreed, so you don't have to worry" he said. "You are unbelievable", replied a white-haired woman with sad eyes, "that poor girl just lost her parents and some strange adults are already deciding her future without her knowing. Her aunt must not even care about her, giving her up to some random marriage just for money. But the worst part is that you are not even asking Shoto if-"

"Silence", stated Enji Todoroki with a frown scary enough to make his wife shut completely. "I'm guaranteeing our son's future. Do you have anything against it? Shoto already has a quirk powerful enough to fight better than any hero I know, with that girl's healing by his side he can train without restrictions and assure good descendants. We will meet her tomorrow afternoon, and I hope you will cooperate". With that, the man exited their bedroom and went back to train with their 10 year-old son. All Shoto's mom could do was to gaze at his son with a worried expression, she was aware that if she said anything it would only make things worse.

The woman knew her love for her youngest son was bigger than her fear of her husband, then, why couldn't she do anything to protect him? That was the question that had kept her wake at night since his quirk had manifested. One could say she didn't care enough about the boy, but that would be a total lie, the truth was that she loved him with all her heart, but the physical and psychological damage she had faced wasn't in vain. Each day was a new battle, a new lost battle to herself, watching her son getting hurt and not being able to defend him, feeling her breaking point closer everyday.

The next day arrived, and with the girl accompanied by her aunt did too. "Listen, Shoto", his mother told him while kneeling in front of him to talk face to face, "the person you will meet now is a girl your father wants you to know better, she will probably spend some time with us from time to time and join your training so you—-"

"Mom, I know father is arranging a marriage for me, I heard your conversation a few days ago, I'm sorry. Even if I don't agree, nothing good will come out of it, either for me or her", Shoto interrupted, "I thought about it last night, and I decided I will make no objections, at least until I have a strong reason. Don't worry, mom, I won't let that girl or me go through what you have been", stated Todoroki with a stern look. His mother couldn't said anything more, a knot in her throat made her feel she could burst in tears with just opening her mouth, so she just gently grabbed his son's hand and went to the garden where they were waiting for them.

There, they met the little girl who apparently would become his bride, she was hiding behind her aunt, who was talking with Enji. Shoto's first impression of her was rather good, she seemed shy and had a cute overall appearance, with her hair in low short pigtails and freckles that gave her a girlish look. "We have been waiting for you, good thing you finally arrived", said Endeavor in an angered manner, "this is my son, Todoroki, he has the hot and cold quirk". The boy made a small reverence to the strangers after his father's presentation. "Then, introduce yourself, kid", said the middle age woman while grabbing the girl's arm. "N-Nice to meet you, my name is Izuku, Midoriya Izuku", answered the green-haired while fidgeting with her fingers "my quirk is Compression healing, I can make bruises and internal body damage really small so they vanish. Although if I do it in a determined dimension it may harm the person, like a traction effect. I can also heal traditionaly like my mother, but since I can't control it quite well with my hands yet, the easiest way is by mouth-contact", said while blushing.

"As I thought, your quirk is quite useful, indeed. Why don't you get to know Shoto better here while the adults talk in the other room", even if Endeavor said it like if it was a suggestion, but they were already gone and left the children with no other option. As expected, it was very awkward, none of them said anything for ten minutes. The little girl started fidgeting and saw something that caught her attention. "Is it okay if I grab that?", asked Izuku shyly while pointing at a lily that was nearby. Shoto just nodded and watched her pluck the flower and then nibble the petals one by one, a sight he definitely didn't expect. "By eating flowers I recover some energy, and they are pretty tasty too. My aunt says it looks disgusting so she had prohibited me to do it at home, I am glad you let me have one", she added with a genuine smile. Afterwards, it became easier for them to interact, they began to talk about school, TV shows, funny things that had happened to them, but mainly about All Might, the favorite hero of both.

When they ran out of topics, Izuku proceeded to say something she had been trying to say from the beginning, "I am not dumb you know", she said while looking down at the leftover flower stalk, "I know they are going to arrange a marriage between us. Ever since my parents died, my aunt have received several proposals for quirk marriages, some are even with men who are 10 years older than me. I really don't know how I should feel, many important things have happened in such a short time it all seems like a dream, or nightmare? But even now, you don't seem like a bad person to me. I think I can bare to be your fiancée until something really important happens, after all, they can't obligate us", only after finishing her statement, Izuku thought trough what she had been saying and began apologyzing nervously.

"I wouldn't mind either", said Shoto while showing her a sincere smile, "since you will be coming here often, I'll ask mom if we can grow more kinds of flowers for you". "That would be nice", replied Izuku with flushed cheeks. Immediately after, the three adults returned to the garden and said each other goodbye. His father then explained Shoto the whole situation, Izuku would be coming a few days per week to help him train and get to know his family better. At first, Enji was not a fan of this idea, he believed interaction between them wasn't really necessary, but his wife insisted it would be the best for them. Also, they won't have a proper engagement until they both reached legal age, this was the condition Izuku's aunt made in exchange of the other rules.

Days moved on, they became weeks, and fastly it had been months since the first meeting. Izuku went to the Todoroki manor almost everyday, there, she usually sat quietly by the training ground and waited to heal an exhausted Shoto by the end of the afternoon. On the days Endeavor had other things to do, they just chated and took strolls in the garden, sometimes they played with his older siblings, who loved Izuku as a little sister. His mother had also became quite fond of her, it had became an habit of hers to give her a different bouquet of flowers every week. To the small boy, those days were easily his best childhood memories. It was more than a relief to have someone waiting for him at the end of each training, too see her concerned face and feel her palms on his wounds. For the first time, he could say his father had made a good decision.

However, without him noticing, his mother's state had been becoming worse. She managed to keep her cool in front of Shoto, but the truth is she was now completely damaged. "I don't know if I can bear it, each day his left side looks more and more like his father's. And that poor girl, everytime I see her I can't help but to see myself- I know Shoto is different, he is my dear son, but I still can't-", said his mother with crazy eyes while talking with someone in the phone. "Mom?", asked Shoto from behind with a worried voice. What happened after was so fast he didn't processed throughly until a few days ago, she threw him a kettle full of boiling water in mid of her mental breakdown, burning his left side of the face. After that, Endeavor claimed she wasn't sane enough to raise their children, so he admited her into a psyquiatric hospital for no determined time.

Since that day, he banned himself to use his left side, he knew his father was the one who broke his mother; and the worst part is he didn't do anything to stop it. Training became more violent, Enji pushed the boy to the limit in hopes that he would use his fire quirk, and of course, it never happened. A week after the incident, he met Izuku again for some training, "Shoto, do you want me to cure it?", asked the girl referring to his burn, "if I do it now it won't leave traces, as if nothing had happened", added with a small smile to confort him. However, all it did was anger him more. Izuku reminded himself about the arranged marriage his mother had been through, the fact that she put all her efforts without looking for attention from the boy made him nauseous. The way she looked at him with caring eyes made him feel unworthy. Now, he couldn't bear to even like her, she was the personification of his father's decisions, all his life was already predicted by the man who had killed his mom's soul.

"Stay away", said Shoto coldly. "W-what?" "I don't want you to cure this, ever. You are here just to cure my training bruises, nothing else, don't get too confident". And with that the boy left her alone in the training ground, Izuku began to cry quietly, thinking about what she did wrong or why did she anger him. She was comforted by Fuyumi, Shoto's older sister, who found her curled waiting for her aunt to pick her up. The white haired calmly explained the situation and told her to just give him some time, and that everything would come back to normal. It did not happen.

Time had moved on and they were teenagers now, both of them were in the UA, the best high school they could dream about. Due to some problems, they started living in the dorms from the first day, both of them were happy to say the least, Todoroki could live far from his father and Midoriya could finally catch some air far from her aunt. It hadn't been easy for her, she had to live with several rules and with a loveless home life. Her aunt wasn't exactly a caring person, the only times she was worried about her was when it had to do with the engagement. Izuku had never been hugged by her, or even given a compliment, still, she believed it was her personality and decided to accept it no matter what. She had also forbidden her to use her quirk via mouth unless it was with his fiancée, so the training only focused on her hands and became extremely hard. The old woman had also been controlling Izuku's diet and manners, from the way she walked to the way she spoke, apparently, Endeavor had given her money to convert Izuku into a perfect lady.

As everyday at 8 am, Izuku gave the now handsome young man a lunch she made on her own, hoping it would help him go back to his old self. "Shoto, Fuyumi told me you liked soba so I made my own variation, here", said a now full-grown Izuku, handing him a lunch box shyly. Shoto glanced at his fiancée, she was indeed beautiful, 'the prettiest girl in class 1-A' as some said. Her hair had grown long enough to reach her waist, though she kept it into a ponytail; her freckles remained and gave her an innocent look; she had a well endowed body that kept all the boys in awe; but most importantly, she had kept her good-natured personality, which was mostly directed to Todoroki.

The teenage boy just said 'thanks' and put it into his backpack, before putting his earphones on so Izuku couldn't have a chance to do small talk. "Todoroki, you lucky bastard!", a grape boy shouted, "handsome guys have it so easy, getting bento from Midoriya, arghh, are you dating or what?"

"Don't you know? Those two are engaged, Endeavor said it on a interview a few months ago, although not on their own will I believe", stated Kirishima as he was passing by.

"What?! So are they like boyfriend and girlfriend?! Did I even have a chance?!", said Mineta.

"I don't think you have a chance even if you were the only guy in UA"

"Poor Izuku, even when she makes her best effort to win some affection, he just shrugs it off, the only good thing that boy has are his looks", replied an angry Ochako as defending her best friend. And that's how their daily lives were now, will Izuku manage to heal his soul someday?

(A/N) So what do you think? Should I leave it like a one-shot (sort of) or continue it? Ideas are more than welcome!
