Family is troublesome...but maybe it's a good kind of troublesome.
Uchiha Hatsu was a single child with a big clan backing her up. She saw the benefits of being part of a clan, but sometimes the clan was more trouble than it was worth it. To be part of the Uchiha Clan meant to meet the council expectations and represent the Clan with pride, a single mistake could mean to be repulsed by the clan and later, by the village. Hatsu thought the Clan was problematic and was never enthusiastic on socializing with them.
She would like to say that Watanabe Chieko is going to form new thoughts of her new family, but she is still Uchiha Hatsu, and her preconceived opinions won't disappear easily, so when her mother tells her that there will be some family members going over to see her, she needs to force herself to hide the disgust on her face. Unfortunately, to hide her emotions with a father like Hiroyuki is an impossible feat.
"They are good people. You will like them, Chieko-chan" even though it is a pain to live with someone that knows everything about your feelings, she must admit she got lucky.
It has been almost a year since her birth, and she has been trying to not hide what she does from them—it's probable that she will never tell them about Uchiha Hatsu. They're civilians, she doesn't want to hurt them...or be treated differently...—. They are sympathetic people, explain everything she doesn't know, and somehow don't seem to be weirded out by her emotions/actions. They even talk to her like they would with any other kid—which is something amazing since she is only 1 year old—, because of it, she has noticed that some words are different from her world—nothing that surprising since this place seems to be much more advanced—, but it isn't a problem, she just deduced the meaning of the words with the context.
Part of the reason of her parents' reactions could be the thing they call 'quirks'.
In her mother's words "Part of the population has a 'quirk'. It's a superpower that lets you do different things. For example, my quirk is called 'Peace' and lets me calm and sometimes control people's emotions. Your papa's quirk is called 'Empath' and lets him know the emotions of people around him. That's why he always knows how you feel, and I can calm you whenever you are really sad" And so, almost everyone here has a kekkei genkai. It's possible they think she's like this because of it, and they may be right. If everyone has an original power, maybe this body—or this baby...—had a quirk that brought her soul here. Still, it's only a theory without any type of solid proof.
Right now, she won't worry about how her soul came to this place. Right now, her objective is to walk towards her father without falling. The man moved the crib to the edge of the room, so she could practice there. She stands on her feet and begins her way towards her father.
Watanabe Hiroyuki is a tall man. He has brown skin, honey eyes, and black short spiky hair. He is handsome, but that's not what defines him. Hiroyuki almost always has a smile on his face and is quick to act when people are feeling bad. He isn't shinobi material, and that could be dangerous, but she won't dwell on it. This civilian family is nice.
"Come on, Chieko. We need to dress you really pretty" her beautiful mother, with white skin, dark blue eyes, and light blonde straight hair, is also a kind soul. The woman isn’t as loud as her father, she is graceful in everything she does, and is the most levelheaded of the pair. Yua takes her from the floor when she is about to reach the man—she hears her father chuckle when he feels her childish anger—.
"Aw, so this is the little princess. Your mother dressed you really pretty, Chieko-chan" Indeed, her mother dressed her beautifully. She has a soft purple baby dress that looks good on her light brown skin. There's a little of black hair on her head, but it's still too early to see if it's curly or straight. Her eyes...well, she doesn't understand why no one thinks anything of them. Her eyes are two black pits, two Uchiha characteristic eyes. The shape isn't even similar to her parents' eyes. Genes don't work like this!
The man speaking is her grandfather on his father's side. Both men are like a copy of each other, so she thinks Hiroyuki will look exactly like her grandfather when he grows old. The old man has the distinctive wrinkles of a person who smiles a lot, and his head is full of grey hair. He has not stopped carrying her since he arrived to the house, but she isn't complaining. Daisuke is taller than her father, so she can easily analyze the people going through the house. She hasn't seen her grandmother, so she assumes she already passed on. Her grandparents on her mother's side didn't arrive either.
The house is a little crowded at first, but most of the people are just friends that come to congratulate her parents, and then go after an hour or two. She pays close attention to everyone and classifies them in a list of safe, neutral, and dangerous. No one falls on the last classification, but there are some who look at her eyes and give her a look of disdain, those people make her want to spit them in the face with the excuse of 'I'm a baby, I don't know what I'm doing'. By afternoon, there are only four guests: her grandfather, Yua's brother-in-law and his son. She doesn't see Yua's sister and no one talks about her—like if they were avoiding the topic—, so she assumes the worst and makes a note to herself of never mentioning it.
Togata Kaito looked uncomfortable, walking through the house with the little blonde boy following him—which could mean it was his first time on this house—, but Yua quickly integrates him to the conversation—the pain on his eyes when he saw her mother didn't go unnoticed to Chieko, so there might be a more serious reason for his actions—, and somehow the boy and she ended sitting on her room's floor.
It isn't that weird for adults to want for the only kids on the house to interact with each other, but she would have preferred it if they didn't force it so much. Although maybe they did it also for Kaito, if he really is a single parent that has just lost his wife like she thinks, he may need some words of support.
"Hi! My name is Mirio..." the boy is 2 or 3 years older than her and looks a lot like his father. He must have taken the blonde hair from Yua's family, and its texture from his father. His eyes are a lighter blue than mother's, so...maybe a combination of his two parents? "The adults say you are very smart and..." he continues talking to her just like her parents do. She was never good with people, much less with children—Sasuke hated her...although he hated Shisui too, so it was more jealousy than hatred. They spent much more time with Itachi than he did—, and she has better things to do, so she just ignores him and moves her chubby fingers in some academy exercises. She wants to regain her motor skills as soon as possible.
She may have ignored him too well because the next time she looks up he isn't there anymore. She remains calm and looks around...no sign of him.
Okay.
He may have got bored and went to see the house, they have a big house, so there shouldn't be any reason for him to go out of the house. She crawls through the second floor of the house. Nothing. What if he went out? What if someone kidnapped him? What will her parents say if something happened to him? Even in a baby's body, she is supposed to be older. She should've kept him entertained...
"Hmm? Chieko-chan? Were you searching for me?" the boy is going up the stairs with a sunny smile on his face and a packet of cookies in his hand.
...
She is never going to worry about this brat again. Without realizing it, she forms a pout and frowns at him, which causes him to laugh a little and enlarge his smile.
When they go back to her room, she doesn't dare ignore him again, and ends playing childish games with the boy—with Mirio doing weird faces now and then, trying to make her smile—. The part of her that's bitter with life doesn't want to acknowledge it—she shouldn't, she doesn't deserve it—, but she is having fun.
The time arrives for the Togata family to go—it's late, and they are the only visit still on the house—, Kaito looks better than when he arrived, and Mirio hasn't released her hand since he was told they should go. While her parents try to stifle their laughter, Togata father forces his son to let go of Chieko. The pair gives their last goodbyes and go, then the Watanabe enters the house and the day it's over, or at least that's what would have happened if Mirio was a normal boy. Instead of going away normally, he starts walking backwards, waving his hand in farewell to then trip and get up with a shout of "I'm fine!" and a big goofy smile.
From her mother's arms, she waves her hand in goodbye and can't help smiling too.
"If Mirio is what it takes to make you smile, I think we should invite him over every day" says her father's trembling voice.
What...?
"It shouldn't be a problem. I'm sure Kaito would appreciate a little of help with his boy. Should I text him now?" her mother's voice also sounds a little sad with a hopeful tone.
It wasn't such a big smile, just these corners of her lips pulling a little up, but it may be a bigger deal than she thought. She didn't even notice she hadn't smile since she arrived to this place, which means she is worse than she thought—and why wouldn't she?, after what happened it would be weird if she was alright—, but that isn't an excuse. These people, they are so good, they deserve better, they shouldn't need to deal with a broken person, they should have had a normal baby with which they could play and enjoy life, but they had her...They have her, and she had been such a bad daughter.
She wanted to wait until she could speak without dragging words—she practiced at night—because even though she was a baby, she didn't want to speak like it, but her parents deserve the joy of hearing the first childish words of their baby. Furthermore, she still didn't know who of her two parents wanted to be her first words—it was kind of a big deal among civilians, back in Konoha—, but they were together now, and she had been neglecting them. What kind of child doesn't smile around its parents?
"...love you, pa, ma..." they didn't react, so she repeated it a bit higher "Pa, Ma! I love you!"
She had never been hugged so strongly.
