There's a mystery going on around me. Once, when I emerged from the swimming pool, a friend of mine looked at my soaking wet hair and said, "Whoa! Your hair looks just like Gokuraku-kun's," and fell over laughing. "Gokuraku-kun"? Who the heck is that? The protagonist of some famous manga or something? I know Shinigami-kun, Enma-kun, Akuma-kun, and Jigoku-kun, but who is Gokuraku-kun? What kind of hair does he have? Later, I asked my friend about it, and this was the reply: "Oh, did I say that?"
