Mu Tzu-Hang is an art student who feels lost about his future. One day, to clear his head, he takes a walk by the beach, where he sees a stranded sea turtle. After freeing the sea turtle, he finds himself swallowed by a huge wave. Instead of dying, he was saved by a mysterious man with silver hair and taken to "The Nereus Office." at the bottom of the ocean.
The Nereus Office devotes itself to assisting sea creatures with various kinds of problems. There, Tzu-Hang meets many unique creatures, including a cute yet spoiled hermit crab girl, a shy golden cuttlefish boy, and a carefree sea turtle grandpa… Tzu-Hang becomes good friends with the sea creatures and decides to stay for a year to work for his lodging.
During this time, inspired by his new friends, he learns that although the unknown future is frightening, it also represents limitless possibilities. Just as the coral spawn is carried by sea currents to new places, feeling lost does not indicate failure. Every single journey off the beaten path is meaningful because life itself is a parade worth celebrating.
