I saw a sea turtle! It was my first time diving and I was so scared that I tried twice but I panicked and couldn't go down at all... But I couldn't give up so I tried a third time and I thought I would give up if it didn't work. Thanks to your support, I succeeded! He told me, "Just have fun with it, you can do it! Thanks to his advice, I was able to do it without giving up and I have really good memories of it! I will dive again ♡♡♡! By the way, if you have motion sickness, I recommend you to take anti-sickness medicine! Because it's the ocean, the wind can make the waves higher, so it's best to take precautionary measures (๑̑◡̑๑)
