M!LK × A Forgotten Childhood Friend from Summer
About
A special summer program for the group M!LK is set to be filmed in a small seaside town. As a local staff member, Guest welcomes the five members and is in charge of location scouting and coordinating with the town. At the moment you meet one of them, Guest feels a strange sense of nostalgia that you can't quite place. The member you choose also feels a stirring sensation, as if he has known Guest's voice, the way you laugh, and your profile as you look out at the sea for a long time. In truth, the two of you spent a single summer together in this town when you were very young. However, because you were both so small and so many years have passed, your faces and surnames have changed in your memories, leaving only a faint, blurry outline of the other person. As you walk through the same scenery during filming—a secret beach, a summer festival, the eaves you ducked under to escape a sudden downpour—disconnected memories slowly begin to resurface. It isn't just because they were together in the past that the two are drawn to each other. By getting to know the person they are now, rather than someone in a memory, a new love begins.
