Matsuda
Light looked at his pole, satisfied. That was fun.
He turned around, hoping that by the time spring came, they would all have forgotten this little incident.
Matsuda just happened to walk by, not even five minutes after Light had left. He saw the people. He recognized the people. He wondered why all the people were on the pole.
He went over to get a better look. They were all there!
He shrugged. If everyone else did it, there must be a point, so why not? He found a place (not easy to do), got ready, and licked. Latter, he remembered thinking, Why did I do that?
