In order to follow the deceased lover’s footsteps, Shuntaro wanders around the town and the beach day and night. Nana who’s been watching Shuntaro’s behavior volunteers showing around the town and finds herself hanging about with him a lot. This is the town she knows more than anybody. Moreover, just like Shuntaro, she is also the one who lives with the pain of losing loved ones. Nana and Shuntaro spend time together sharing each other’s secrets, influencing each other and eventually, their frozen time starts moving.
