Mistaaaaaake! XD
So, putting Yamapi's guest spot on Oguri Shun's All Night Nippon on my mp3 player was a mistake for the following reasons.
1) Oguri was being all goofy, at one point even saying that he wanted to be a tour conductor in Hawaii so he could go ALOHA!
2) Yamapi laughed. A lot. I don't think I've ever heard him laugh, it was very cute! There's no confirmation, but I'm pretty sure I looked like this. Which on public transport, not a very good idea.
3) Both Oguri and Yamapi have very nice sounding voices. I'm lucky I didn't miss my stop! *dreamy sigh*
4) Their conversation was very funny, and I kept giggling. See #2 for why this is not a good thing.
I was, however, very surprised at how much of the conversation I understood! Yay me!
