Nagisa Mio, an oceanographer at Shibaura University of Marine Science and Technology, loves the sea but is secretive about her past.

When he returns to Japan to manage a marine development project, he clashes with Mio, who opposes the resort's construction to protect the ocean. As they work together, they fall in love, but their relationship is forbidden due to a shocking secret Mio is hiding.
