Refrain Blue

Yoshihiro Matsunaga, a young man carrying the weight of a painful past, accompanies a group of high school students as their chaperone on a summer trip to the beach. During the trip, he rescues a student named Nao Morisawa from attempting to drown herself. Nao is still grieving the loss of her fiancé, who died in a plane crash exactly one year ago on the same trip.

As Yoshihiro and Nao grow closer, they begin to share their sorrows and discover that both are haunted by loss. Watching over them is a mysterious young girl known as the "Umi Warabe," who appears at pivotal moments. Together, they must confront their grief and find a way to heal their wounds and move forward with their lives.
