It was summer time, and they were all at their vacation spot again.
Miwa had always knew that Kai would rather not go, but came out of politeness. It wasn't that he could read Kai's mind, he just saw the annoyance on his face, and knew he would rather not come.
Now it was near evening, and everyone was playing truth or dare.
"Aichi, I dare you to kiss Misaki!" Izaki teased.
"Eh?!" Aichi looked flustered, and glanced at Misaki, who kicked Izaki in the face.
"Oh, wait! I have a good one!" Miwa cried. He looked at Kai. "Kai, truth or dare?"
"Don't know, don't care." Kai replied lazily.
"Try to laugh! You know, like how regular people do when they hear a joke, or when they're tickled, or something like that."
Kai just gave Miwa an angry glance. Then he looked at the others, who were waiting to hear what it was like. Kamui took out a video camera.
Kai snorted. "Fine. But put away that video camera." Kamui put away the camera, pouting, and Kai let Miwa tickle him in his only ticklish spot, under his knee.
Miwa held in a laugh at how ridiculous Kai's laugh was. It sounded like a sick donkey with the hiccups. The others held in their laughs just fine, but Morikawa burst out laughing. The others couldn't take it anymore and laughed. Thirty minutes past by until they could all calm down.
Kai was watching them with a flustered face, and glared at Miwa, who winked he got up and headed to the cabin.
So you forgot how to laugh, huh?
