One day you went to the beach with Muichiro and your friends, you didn't feel like swimming so you stayed back with Muichiro as he was reading a book on Moon jellyfish

You had a towel around you covering your swimsuit, but he didn't pay attention as he was stuck on the book

Muichiro: "Apparently, on a Wednesday at 1am when it's raining, if you put a lantern on a boat and send it off into the ocean a buch off moon jellies come and float around as make the sea glow it sounds beautiful..."
