No one knew when this formed. All we knew it dated back into ancient times. People didn't understand it till a century ago. There have been hundreds of books published on the history and how to work the system. Those books on how to work the system is more of suckering those who are crazed about romance. It is better to wait till you find your destined lover. The red string was tied around the person's pinky. It doesn't disappear till a person finds their soul mate. It also doesn't show itself till the ages between 20 to 22. If you cut said string, it cancels out the soulmate and you wouldn't be able to find another nor find good chemistry between you and another person. It leads to misfortune. Anyone could see the red string tied in a pretty bow on a pinky but they cannot see how long or short the string is. There are no evidence on if the string is long or short what kind of benefits the couple have.

An auburn haired woman in her late 20's adjusted her purse over her shoulder. She wore a deep blue circle skirt with a cream colored ruffled blouse. Her grey eyes trailed upward at the sign of a cafe. It was the meeting place with her adopted brother. She had been busy with the hospital that she haven't been able to keep up with him or anyone in that matter. She felt guilty so when he ringed her up last week to see if she wanted to go to the cafe in town, she accepted. It was time for her to get back in contact with him. A little bell signaled the workers a customer have entered. She scanned the area for the familiar blond. By the window she saw him. He nursed a cup of coffee inbetween his hands. His long blond hair was tied up into a messy bun. His casual wear was a pair of jeans and a popular band shirt. Over the shirt was a leather jacket. Her eyes softened at the sight of the jacket. He still owned it even after all these years.

She headed to the two-person table and sat down across from him, "Hey you."

Hizashi gave a small smile, "Yo, my favorite little sister of mine."

Katrina huffed, "I am your only sister."

Hizashi's lips widened, "Exactly. No one could replace you. Also don't worry, I'll buy."

A cafe waitress came by with a smile, "Hello! Welcome to Sunshine Cafe. Have you been here before?"

Katrina tore her attention away from her brother to look up at the overly cheerful waitress. Katrina gave a small smile and shook her head. She answered, "I haven't but I just like to have chai latte please."

The waitress quickly wrote it down and excused herself. Hizashi placed his mug down and leaned forward, "It's been a while."

Katrina glanced down at her brother's right pinky. She felt her heart sank. She remembered when he came by her apartment drunk claiming he cut off his string. He didn't care that the other person on the other side of the string would become soulmate less. He didn't want to go through that heart break again. He had a serious relationship before the red string appeared. When it appeared, he felt hurt that his red string didn't match with hers. He felt even more hurt when the woman who he thought was his soulmate despite the red string went and cheat on him. Katrina felt it was an excuse to leave her brother. It was a horrible way to end a relationship based on that person not being your soulmate. Quickly she glanced down at her own right pinky and tied around it was her red string. There would be times she would feel a tug but didn't understand the meaning of it.

Katrina let out a haggard sigh, "I know. I am sorry. I am having a hard time balancing work and life. After this, I'll definitely make an effort, I promise."

Hizashi pursed his lips, "Uh huh. The most popular line."

He leaned back stretching out his legs. His legs went on either side of her chair. Katrina defended herself, "I am going to make an effort, Zashi."

The waitress came back with Katrina's chai latte. Katrina thanked the woman. The auburn haired woman sipped on her latte. Hizashi studied his sister while she was occupied. He saw the red string still tied around her pinky. He pointed to her pinky, "Still haven't found him?"

Katrina scoffed, "I wouldn't know what to do if I did find him. The hospital keeps me on call."

Hizashi leaned his head back to stare at the ceiling. He moved his head back and leaned forward again. He spoke softly, "I wish you didn't have that quirk of yours."

Katrina glanced at her hand. She opened and closed her fist. Her quirk was a healing type. Just by touch, she can heal someone and transfer the pain and wounds to her. That was the reason for the hospital keeping her on call. It is rare for someone to have a healing type of quirk.

Katrina reached over and lightly grasped her brother's hand, "I know... If I was a pro-hero like you, it might be a little different."

Hizashi bounced back with a clap of his hands. He had to remind himself to keep control of his quirk or he would make his sister and everyone in the cafe deaf. He piped up, "How about this? I can gather a few of my teacher pro-hero friends and we can go do something."

Katrina shifted in her seat, "I don't know about that..."

Hizashi gave a little pout, "You said you'll make an effort."

Katrina lightly argued, "With you."

Hizashi rolled his eyes. He sipped on his coffee. Katrina could tell by his body language he wasn't happy. Katrina let out a haggard sigh, "Alright fine. Fine. I'll try to talk with the hospital head about giving me a couple actual days off."

Hizashi's lips turned upward, "Great! I'll send you the details about it."

Katrina buried her face into her cup of chai latte. She doesn't know how to bring this up to her hospital head. She tried before but they always shot it down. The only way she could think is telling them she would transfer out to another hospital, a competitor even, to at least have a couple days off each week.

The auburn haired woman glanced at her phone. Her blond adopted brother texted her the details that night they met at the cafe. She was able to speak with her hospital head. They were scared of loosing her as a valuable asset so they changed the work environment. Like mentioned before, healing quirks are rare and very sought after for employment. She could not think to leave one of the best hospitals in Japan even though the work environment sucks. She felt a light tug on her pinky but she ignored it. This little get together is the first time she have been out with other people. She took in a deep breath and headed inside the restaurant. Hizashi said one person in the group refused to do anything other than the going out to eat. Katrina had a feeling it was his suggestions that weren't everyone's favorite. She don't blame them. Hizashi is a little music rocker at heart. Concerts aren't everyone's fancy.

Katrina finally found the table where some people were sitting. Her brother waved her down, "Over here, Kitty Kat!"

She felt the tips of her ears warm up. She quietly moved towards the open seat by her brother. On the other side of the table was a purple haired woman and a blond man. Hizashi leaned forward with his hands clasped together. His chin leaned against his clasped hands. A smile was playing on his face as he spoke, "Guys, this is my baby sister, Katrina. Kitty Kat, this is Nemuri Kayama and Toshinori Yagi."

Katrina noticed the blond haired man was stricken with health problems. She was already analyzing what needs to be done to improve his health. Hizashi nudged her in the arm with his elbow, "Katrina."

Katrina blinked then blushed, "Sorry. Anyways it's a pleasure to meet you two."

The purple haired woman gave an amused smile, "It's okay. I was surprised when Yamada came and asked if we wanted to go out for dinner to meet his little sister but you don't seem so little."

Katrina glanced at her brother quickly. He seemed to be occupied as he was looking at his phone. Katrina guesses this isn't everyone who would be joining. Katrina cleared her throat, "Actually I'm the same age as Hizashi. His parents adopted me as a child. My parents died during a villain attack."

Toshinori cleared his throat and looked down then up repeatedly, "I... I am sorry for your loss."

The auburn haired woman felt her red string tug once more. She ignored it as she reassured her brother's friend, "It's quite alright. They sacrificed their lives while saving others. I am proud of them."

Toshinori nodded. A waiter came by the table, "Are we all ready to order?"

Hizashi answered for the group, "Not yet, listener! We are waiting for one more person."

Nemuri questioned the blond radio host, "You were able to convince him to come?"

The radio host gave a light whine, "He's the reason why the plans because at a restaurant."

The waiter left the table to their own devices after taking quick drink orders for now. The thin blond pointed out, "I think this was a better choice versus the concert you spoke about."

Katrina felt her brother lightly smack her arm to get her attention. He groaned, "It was a BTS concert, Kitty Kat."

Katrina shook her head at her brother's antics with a small smile on her face. Her string tugged harder than ever before. A monotone voice interrupted the table's conversation, "I'm sorry I'm late. I didn't want to come."

Hizashi huffed at the person that stood behind Katrina, "I said I was going to add in a cat cafe for you, Aizawa."

Nemuri took Hizashi's attention away from the person behind her, "Hey! How come he gets more than a dinner?"

Katrina didn't hear the two argue as the new person sat down next to her. The black haired man turned to her, "So you're his 'little' sister. Name's Shouta Aizawa."

Katrina took in his appearance. He wore black shirt and pants and his hair was pulled up into a small bun with majority of his hair down. He had a light beard and mustache. She couldn't help but think it looks good on him. Katrina held out her hand for him to shake. He slowly placed his hand into hers as she introduced herself, "Katrina Ayano."

The two felt the red string's weight lift off of their pinkies. Katrina blinked. Shouta raised his eyebrows. It took the woman a second but she pulled her hand away as if he was a hot stove. Katrina stood up immediately, "I... I uh have to go to the bathroom!"

She disappeared from sight. Toshinori was the only one who saw the whole exchange happen. A small smile played on his lips. Hizashi turned to his best friend, "What did you do? Did you scare her off?"

Before the black haired man could answer, Toshinori answered for him, "They are soulmates."

The only other woman and the radio host immediately looked at Shouta's now barren pinky. Nemuri smiled big, "Well, I guess a congratulations is in order?"

Hizashi kept his eyes on his friend's pinky. Shouta didn't know what to say and neither did the 'older' brother. Shouta was about to rise out of his seat but Hizahsi's hand was planted firmly on his best friend's shoulder, "No you'll stay."

Hizashi knocked on the bathroom door. A woman exited out of the single bathroom and it wasn't his sister. His lips went into a firm line. He looked around the area till he decided to head outside. He could see a lit end inbetween someone's fingers. Another person was around said person smoking as well. Hizashi headed to the person he saw first, "Katrina... What are you doing?"

Katrina turned to her brother and coughed out the smoke. She panicked. Hizashi grabbed the cancer stick out of her fingers, "That's bad for you. You know it too."

The person by the two step up to the plate, "Woah man, easy there. If the lady wants to smoke let her."

Hizashi turned to the man and gave a glare, "Woah man, easy there. I am guessing you're the one who lent her the cigarette. How about you run along or I'll make you?"

Katrina placed her hands on her brother's arm, "Hizashi... Come on don't."

He allowed his sister drag him away. Once they were away from the smoker, she gave a few more coughs. Hizashi crossed his arms. He was frowning. Hizashi scolded, "You don't smoke. What was that out there?"

Katrina started to pace, "I... I don't know. I am afraid, you know? After what happened with you, I thought I could handle with meeting my soul mate but thinking back what happened to you I don't want that to happen to me."

Hizashi uncrossed his arms and placed each hand on each side of his sister's shoulders. He bent down to her height. She could see his green eyes staring into her. Hizashi spoke seriously, "Of all people, I rather you be with Shouta. I don't want you to be scared of this whole soul mate thing. What happened to me happened to me, not you. It goes to saying I trust you with Shouta. I never seen or met anyone who is as loyal and hardworking as him. He may come across as lazy but he puts in his work."

Katrina shrugged off her brother's hands. Katrina looked away, "That still doesn't help me feel better. I... I think I am going to go home, Zashi. I'm not feeling all too well."

Hizashi's lips went into a firm line as he knew it would be difficult to convince her to stay. To at least get to know her own soulmate. So he watched her head to her car and leave.

Dressed in scrubs, Katrina looked down at the clipboard in her hands. It was of a recent patient who took a blunt force trauma to the head. She couldn't take away his pain and trauma all at once but in increments. A familiar monotone voice brought her attention elsewhere, "Would you like to come with me on your lunch to just talk?"

She felt warm inside but she pushed the feeling down. Katrina refused to look up from the clipboard, "No, I am good. I brought my lunch today. Thank you for the offer though."

The nurses have been gushing over her lack of red string and wondered who the lucky man was. Katrina didn't give them any information. She refused to as she didn't want to get hurt. The same monotone voice sounded closer, "I was gong to take you to the new cat cafe that opened up down the road but I guess..."

His words were trailing off. She put in a mental note to smother her brother in his sleep with his pillow. Katrina looked up with a huff, "I told you-."

Their eyes met and she felt like she was on cloud 9. Her words trailed off into nothingness. He had his hands shoved into his pockets and his medium length hair was down. She gulped," If I say yes to this, would you leave me alone and we pretend this whole thing never happened?"

Shouta gave a curt nod. What both of them didn't know, the more time you spend with your soul mate the harder it was to ignore the pull.

Old cats. Fat cats. Kittens. Sleeping cats and even the energetic cats were all over the place. The two sat on little futon squares with a tiny table between them. On there was a plate of pastries and two boba tea drinks. Shouta had a few cats around him. Two were on each shoulder and two were sleeping in his arms. Katrina played with a kitten with a little fishing pole toy. Shouta stayed quiet. He studied the woman in front of him. She had her hair in a braid. Her scrubs were of emerald which helped bring out her eyes and hair. When Hizashi brought up the idea to take his sister to the cat cafe, Shouta was glad the woman also liked cats. He would think the woman would enjoy his blond tabby at home and would get a kick out of his name. Shouta asked, "What do you like to do?"

Katrina paused briefly in her play before continuing. She answered, "I work. There isn't much I can do."

Shouta knew the feeling. He works as a pro-hero at night then in the day he is a pro-hero teacher for upcoming heroes. Shouta nodded, "I understand. I am the same way."

Katrina glanced at him, "If you knew Hizashi then you are a pro-hero as well, I am guessing."

Shouta nodded once again, "Eraserhead is my name. I teach as well with Hizashi."

Katrina turned her vision back onto the fiesty little kitten. It was a no brainer that the man across from her loved cats. He has four on him. Katrina stopped with the toy fishing pole and let out a heavy breath, "I am sure you know why I am hesitant on being soulmates."

Shouta blinked, "I have an idea. It has to do with your brother's past, doesn't it?"

Katrina fiddled with the pole. The kitten tried to swat at the pole and the crinkle ball at the end. It obviously wanted to continue to play. Katrina finally turned to the man, "Yes and no. Yes as I am afraid what happened to him would happen to me. No because this whole thing is terrifying. How does one know that the person on the other end of that string is truly your soulmate? What happens if they are the worse person to live on this planet? We don't know."

Shouta added his input, "Well... You won't know unless you try it. On Hizashi's past, I would never hurt you in any way."

Katrina's lips turned into a firm line of uncertainty. Shouta lightly petted the sleeping cat's head in his arms. He took turns on each cat in his arms. He proposed an idea, "How about this... For the sake of this whole soul mate thing, we can go out on a few dates and see where it takes us. If you do not like the way it is going, then you can leave if you want. I won't stop you."

The auburn haired woman tossed around her pros and cons of the proposition. Finally, she came to a conclusion. She nodded, "Alright. Let's do that."

Time went by and a nervous woman paced in a small room. Thoughts filled her mind of what could go wrong and what not. A knock took her out of her mental place. She called out to the person on the other side of the door, "Are you ready, Kitty Kat?"

The door opened revealing a suit wearing Hizashi. His hair was down completely. For a second she was envious of how straight and untangled his hair is. She answered him, "I am nervous."

A smile was brought onto his face. He entered the room closing the door behind him. He placed his hands on his sister's cheeks. His thumbs lightly rubbed against the apple of her cheeks. He spoke softly, "You're alright. You should see him. He's more nervous than you, Kat. Now I want you to build up all that courage and walk out there like you own that show."

Hizashi pulled away from his sister and had a full look of her. He whistled, "He's going to love it."

Katrina blushed, "Shut up."

He held out the crook of his arm, "Ready, my favorite listener?"

Katrina looked at the mirror of herself then at the arm of her brother. She gave a nod, "Always."

The brother and sister duo headed out and the show must go on. He walked her down the aisle. At the end was a black suit wearing Shouta Aizawa. His hands were clasped in front of him. She was sure Hizashi had to scold him for putting them in his pockets. It was always a habit of his to shove his hands in his pockets. Hizashi released his sister into the hands of his best friend. Shouta and Katrina turned to each other. She gave a soft shy smile where he gave her one of his one of a kind smiles. It wasn't the creepy ones he does to scary the children he teaches but it was a genuine smile. She figured that out after a few months and she dropped in at his work establishment.

Shouta leaned forward and whispered to her, "You look beautiful. Aren't you glad you took this risk?"

Katrina met eyes with her soul mate and smiled, "Oh shush."

Shouta's smile widened. It was a pleased with himself smile. A clearing of the throat brought everyone's attention, "We are gathered here today..."
