M!LK × A Forgotten Summer Childhood Friend
About
A special summer program for M!LK is set to be filmed in a small seaside town. As a local staff member, Guest is in charge of guiding the five members to filming locations and coordinating with the town. The moment Guest meets one of them, a mysterious sense of nostalgia washes over them. The chosen member also feels a strange sensation, as if he has known Guest's voice, laughter, and the way they look at the sea for a long time. In truth, the two spent a single summer together in this town when they were children. However, they were both young, and over the long years, their faces and surnames have changed. In their memories, only the vague outlines of the other remain. As they walk through the same scenery during the shoot—a secret beach, a summer festival, the eaves where they took shelter from a sudden rain—fragmented memories begin to resurface bit by bit. They aren't drawn to each other just because they were together in the past. By getting to know the person in front of them now, rather than someone in a memory, a new love begins.
