This part of the story is set 5 years after Haku got to the Human World. So they are 18 now. Enjoy.
She stood in her long, white, beautiful dress. After months of planning, the day was finally upon them. Her dress was simple but elegant. It was long and hugged her body perfectly. The only detail was the beading that formed intricate shapes along her sides giving the illusion of an hour glass. Her hair was pulled in an elegant updo and her makeup with very simple. Foundation, blush, eyeliner. On her feet were white ballet slippers. The music morphed and it was her cue. She stood at the double doors that led to the main church where her wedding was to be held. They opened and she saw Haku waiting for her. Her throat had a lump the size of a fist in it when she saw the emotion in his eyes. Smiling, Mai walked down the aisle to meet her future husband.
Chihiro lay on her bed. She was supposed to be there. She was supposed to be his best woman. He had asked her to do it when they announced their engagement. She swallowed against the lump in her throat and nodded. She had to excuse herself or she would start crying all over again. All she did was cry since he chose Mai, again. They tried to make it work between them, tried hard, but nothing seemed to bring back that spark that they used to have. Finally Chihiro gave in. Haku wasn't going to break up with her, so she ended it her junior year. She told him to be happy, so he went back to Mai. Chihiro was broken up about it, a part of her wanted to be sadistic. To tell him that she didn't want him in her world anymore. She knew that all she had to do was say the word and he would have to go back to the Spirit World, but she couldn't do it. She wouldn't have been able to bear being away from her best friend.
She dropped out of the wedding that morning. She claimed she had the flu. In reality she couldn't face seen the finality of him getting married. She couldn't stand seeing it. Glancing at her closet door she saw the dress that had been picked out. It was a green mermaid dress. She got choked up when she saw it and ripped it off the hanger. She opened her door and threw the thing out into the hall. She glanced at the clock and saw that the wedding should have started already. Her chest was hurting and, without thinking, she went out to the hall and got the dress. Putting it on, she recalled when they got it. Haku had gone with them and Mai was picking out the dresses. She tossed that particular one to Chihiro, who put it on quietly. When she stepped out, she saw Haku's eyes go wide. The dress hugged all her curves perfectly. Mai didn't seem to notice his reaction, so she told Chihiro to get it.
She barely made it to the church on time, but she didn't go inside. She sat in her car and let the tears fall. She knew that the decision that she was about to make might ruin everything. She might lose them both forever, but she had to try. She got out of her car and stood outside of the double doors.
"If anyone has any reason why these two should not wed, let them speak now or forever hold their peace." The minister was saying.
Chihiro peaked through the little window and saw Mai turn around and glare teasingly at the guests. Bracing herself she pushed opened the doors.
