Yume is my OC. She's basically Kai's little sister. There's going to be some OOCness in this story. Don't like, don't read.
---------------------------------------------------------------------
Yume was walking down the street, heading to Card Capital. She held Misaki's present in hand. It was the lavender haired girl's birthday and all her friends were invited. Everyone including Leon. Kai's little sister had a crush on the blondie. Many boys used her to show off, but dumped her when they found a better girl. Her heart had broken into pieces and was never fixed. But when she met Leon for the first time, he was kind, and very sincere. Yume's heart started to heal. On his birthday, she plans to confess to him. As she was about to open the door to the store, he heard a voice that breaks her heart into pieces again.
"Misaki, will you be my girlfriend?"
Yume stood still and didn't knew what to do. Her crush loved someone else. Yume waited 5 minutes before entering the store, pretending not to know anything.
"Tanjobi omedatou, Misaki-chan!"
"Arigatou, Yume."
"Ne, Yume, Leon confessed to Misaki earlier and they're dating now," Miwa said.
"Hontouni? Omedatou, Misaki-chan, Leon-kun."
"Arigatou."
Kai was sitting quietly with a poker face. Yume saw sadness in his eyes. She remembered that Kai liked Misaki. She signaled him to make an excuse to leave. Kai saw the sign and nodded.
"I need to leave. I have something to do and I forgot it."
"Something to do... Oh right! I forgot too. We need to leave," Yume said, catching to his brother's plan.
"You really have to leave?" Aichi asked.
"Yeah. Bye-bye, then."
The siblings left the store and ran back to their apartment. They soon arrived and locked the door. Yume started crying as she sank to the floor. Kai held her to his chest and carresed her head.
"Yume, Leon is an idiot for picking Misaki over you. You are one of the prettiest, smartest girl I know. If Leon can't see that, he made a wrong decision," Kai said, comforting her.
"Misaki-chan made a wrong choice to accept Leon when she hasn't know your feelings yet," Yume said, trying to do the same.
'Siblings can understand each other well, don't they?'
