Okay..first of all, this is an alternate universe story, so it means no shinigami, no hollow, no arrancar, and no dead people here... :)

Karin is herself, she still has Yuzu as her sister and Ichigo and her brother. But Toushiro is different, he is wealthy and powerful in this story. He is extremely ooc though, because he likes to tease Karin so much. The background that you need to know between them is that they were childhood enemy, they don't like each other that much in high school. This story is set when they grow up.

Desperation definitely made people do strange things, such as staying up all night to study for a huge test or asking a favor from someone they didn't know, or in Karin Kurosaki's case, writing a letter to her childhood enemy, Toushiro Hitsugaya. Under normal circumstances, she would have absolutely nothing to do with him. Both of them had made sure that they made each other's lives nothing but hell in high school.

At twenty, and freshly graduated from Tokyo University just a few months back, Karin wouldn't have thought that she would have given up to a ridiculous thought like this one. Most likely he would say no to her request and it would be a proof that getting helped from the old enemy was impossible and a bad idea in the first place. The reason why she did this? Well, everything was her ex boyfriend's fault. If he hadn't cheated on her with a girl called Hinamori, none of these would have happened. She wouldn't be having this big problem of finding a date to go to her brother and his fiancé's wedding where her ex boyfriend was a best man.

Karin sighed and sealed the letter; sending the letter was going to be the first thing she did when she woke up in the morning. Collapsing on the sofa, she took a deep breath and looked at her sister's picture on the shelf.

"Do you think I'm crazy Yuzu?" She asked touching the picture at the same time.

...

A few days later, Karin was sipping her coffee and reading a newspaper. The wedding was in a week and she desperately needed a date within three days before she went back to Karakura town where the wedding took place. She was thinking maybe she could ask one of her guy friends to go with her, but that would mean nothing because Masaru, her stupid boyfriend, would know immediately that she had no date. She still hadn't heard back from Toushiro and although it was very disappointing because she had no idea what to do, she wasn't surprised why he didn't answer her. Until now she didn't even know why she decided to ask her childhood enemy to help her with this. Maybe it was because Masaru didn't like him that was why she considered him as a perfect choice. But this was definitely the craziest idea she had ever had.

Just before she decided to stop caring about this, she walked to her mailbox to check if she got a reply from Toushiro or not. This was going to be the last time she checked her mailbox because she had to leave her apartment within couple days. If there was no reply from him this time, she was going to give up and would have to go to the wedding by herself. However, when she opened her mailbox, she found that she got a letter from him. She took a deep breathe before opening a letter.

Dear Karin,

I would love to accompany you to your brother's wedding.

It would be greatly entertaining to make a joke on Masaru, or should I say your ex boyfriend.

I will meet you tomorrow's morning so we can make some arrangements.

Toushiro Hitsugaya.

Karin glared at a letter she just got, but since she was so desperate she didn't have a back up plan. So she decided to ignore his obvious disgust at her and her ex boyfriend. After all this would be terrific idea to have a revenge on him too. She knew Toushiro was a perfect choice for her plan. He was rich, powerful, and influential, and despite the fact that she didn't like him, she knew he was good-looking, personable, and charming... when he wanted to be, that was.

'Shit! I'm insane' She thought as she looked at the letter again.

...

The next day, Karin woke up early in the morning to clean up her apartment. She knew Toushiro was coming today, and she wouldn't give him an opportunity to complain anything about her apartment. She also packed her bag ealier to make sure that she didn't forget anything. She needed to talk to Toushiro about the place where they were going because the whole wedding ceremony was going to take place in their hometown as it was where her brother, Ichigo, and his fiancé, Rukia met. She was thinking of what she was going to do once she got there when she heard a knock on the door. 'It must be him.' She thought.

"Hey," She said as she opened the door, trying to be nice. "Thank you for doing this."

"It wasn't for you," He smirked and replied as he stepped into her apartment. "I have my reason. Plus it would be nice to see Masaru's face once we get there."

"Well, I'm glad that you care so much." She snapped and glared at him before closing the door.

Of course, it meant nothing to him because he just continued to smirk. And that smirk was really annoying for Karin. She couldn't understand why he couldn't be decent like ordinary people. But the better question that popped up in her mind was why she decided to do this in the first place.

"So how are we going to get there?" He asked as he sat on the nearest sofa comfortably in a Hitsugaya-ish manner.

"By car of course, or you have a better idea?"

"I'm just messing with you," he replied then snorted. "Seriously, you never change. Anything you want to talk about before we go there?"

"With you?" She looked at him in disbelief. "I don't think so."

"You know if we are going to be in love, we should act like it."

"Listen, we don't need to and I don't need to tell you anything because it's none of your business. Besides we are just pretending! I believe you know the meaning of pretending."

"And I believe you know exactly what I mean. Let's face it. No one is going to believe we are together unless we act like it. So in order to make it believable, it has to come from both sides."

At this Karin who had been trying to protest whatever he said but found herself speechless. Obviously nothing had changed because he was still mean to her as he ever had been before. But she knew he was right, they had to act like it. Although another side of her conceded that she wasn't making that much of an effort, the stronger side said that he had to make more of one too. They had been enemy since high school and they had been negative about each other since then. Honestly, what did he expect from her? Did he expect her to run to him with outstretched arms and say thank you? Oh, she didn't think so.

"So," He asked all of a sudden. "Do we go straight to the party or what?"

"Yes," She replied looking at him carefully.

Toushiro nodded. He was quiet for a moment as if he was thinking about something.

"So, what am I supposed to wear?" He asked finally.

Karin immediately rolled her eyes. She was trying to sense if he was just trying to make a complete fool of her or was really curious about he was supposed to wear. She looked back at him, slightly impatient, trying to get her answer.

"Don't you know?"

Toushiro just looked back at her with an amused look on his face.

"What are you looking at? I'm asking you." She snapped.

"You are amusing." He replied and chuckled.

"What the hell are you talking about?" She asked angrily.

"Never mind," He shrugged nonchalantly. "If you don't answer my question, I guess I will just go in my boxers."

"You will not do such things." She said dangerously. She knew the answer to her question now; he intended to tease her and she wouldn't allow it.

"Well, I have no idea you are so ashamed of showing me to the public," He smiled sweetly. "After all you ask me to help you."

"I don't care." She glared at him, obviously annoyed with the remark he just made.

"If we are going together as a couple, we need to sound like we are intimately acquainted."

"And if you don't stop making these smart remarks," She warned him. "You'll soon become intinately acquainted with my fist in your face Toushiro."

"Been there, done that. Remember the last year of high school, right before the graduation?"

"Whatever," She sighed, finally giving up. "I'm wearing a blue kimono. You figure out what you are supposed to wear."

"Okay" He replied smirking.

Karin thought that she couldn't stand Toushiro anymore, so she walked to her kitchen and prayed that he would just leave soon. The idea of having him as her date on the wedding day was unbearable enough.

"You know, we are going to need a story." He said simply.

Karin stopped walkimg immediately. Although she almost made a remark to what he just said as well, she also realized he was right. His tone had no mockery in it at all; it was just an intelligent statement of fact. They did need a story if they wanted to make it believable.

"You are right." She said.

"Of course I am."

"Oi, shut up," Karin snapped. "We will think of something when we get there."
