Kuwabara really wished he could hear what Shiro and Shizuru were saying as he watched them through the café window. He especially wanted to know what was said when Shizuru started blushing; he'd never seen his sister look embarrassed before, and Kuwabara didn't like it that Shiro seemed so pleased he'd managed to embarrass her.
"How long are they going to stay in there?" Urameshi grumbled. "I'm getting hungry."
"You don't have to stay," Kuwabara pointed out.
Urameshi's reply was cut off when Shiro and Shizuru got up from the table. Kuwabara dragged Urameshi around the side of the building so they wouldn't be spotted.
"Where are they going now?" Urameshi asked.
"Shizuru said they might go to the movies," Kuwabara told him.
The two boys followed the couple, and they went to the movies as predicted. Kuwabara bit his lip in consternation. "I don't have any money to get us in," he said.
Urameshi rolled his eyes. "I know a way to sneak in."
"But isn't that wrong?" Kuwabara asked, frowning.
"Would you rather break a rule or leave your sister alone with that guy?" Urameshi asked.
"Show me," Kuwabara said.
Urameshi led him around the back of the theater and showed him a window to the men's bathroom that didn't latch. They snuck in and found their way to the theater Shizuru and Shiro were in. There were few people in the theater at that time of day, and they were very spread out. Kuwabara and Urameshi snuck into some seats two rows behind Shizuru and Shiro as the movie started.
Kuwabara grumbled when he saw Shiro put an arm around Shizuru. He glowered when Shiro leaned close and whispered something in Shizuru's ear. Then he gaped as the teens started kissing.
