Today was rainy and overcast, so I couldn't see the starry sky I'd been hoping for, which was quite disappointing. However, Mr. Kobayashi, the guide, was incredibly kind and friendly, which warmed my heart. He was very attentive and chatty during the pick-up and drop-off, and his efforts to explore the jungle life during the tour were wonderful. Perhaps I should return to Miyako Island; next time, I hope to see a beautiful starry sky.
