Yumi, a city girl, returns to her rural hometown for the summer, only to find it unchanged, yet suffused with an unfamiliar tension. She meets Tatsuya, a local man who claims to have known her in her childhood. As they embark on a journey of rediscovery, they find themselves drawn into a web of unspoken desires and long-buried memories. Their encounters become increasingly intimate, from shared baths in the traditional onsen to passionate moments in the lush bamboo groves, each touch igniting a fire within them, threatening to consume their delicate dance of remembrance and revelation.
