Mako Mochizuki, a high school freshman with a penchant for losing her way, finds solace in capturing the world through her camera lens, a passion inherited from her late grandfather. Feeling adrift after his passing, Mako is beckoned by Kei Akahoshi, a fellow photography enthusiast, to visit Lens Inn, the boarding house associated with their school's photography club. Eager for a fresh perspective, Mako accepts the invitation, hoping to not only explore new scenery but also rediscover herself. En route to the inn, Mako's camera lens captures a fleeting image of a puppy and a mysterious boy, sparking her curiosity. Upon arrival, she encounters Omochi, the inn's furry resident, and his enigmatic caretaker, Mitsuru Amemura, a reserved first-year student. Despite Mitsuru's initial reluctance to be photographed, Mako uncovers a hidden charm behind his guarded facade, leading to the gradual blossoming of an unexpected friendship.
