Is it just me, or did Osatou-san seem to see this coming right from panel 2? I think Tani-san shouldn't be afraid to widen his horizons a bit, by mixing it up with at least one other random song to surprise everyone with, or something. I guess this is why Tani-san doesn't show up in the karaoke stories.
Same song over and over and over and over and over and over again. But the title seems a bit offensive to the Filipino Community, but it's fitting.
Truth be told, I was kind of surprised at the title for a bit. Not offended by it, though I do know that the name has historical significance here in the Philippines.
