In the serene town of Kamakura, Haruto and Miyu were inseparable childhood sweethearts. Their favorite place was beneath the majestic willow tree by the riverbank, where the soft rustling leaves seemed to echo their laughter. This spot was their secret world; there, they exchanged dreams, shared fears, and promised to stay close forever.

One chilly autumn day, Haruto arrived early at the willow tree, expecting Miyu to be there as always. But she never showed up. Days passed, and then weeks, but Miyu was nowhere to be found. Her sudden disappearance puzzled everyone around her, and no one could explain why she left or where she had gone. Though silent and hopeful, Haruto visited the willow tree every day after school, clutching the memory of their bond.

As years flowed by, Haruto blossomed into a confident, handsome young man who became popular at Kamakura High. His charm and sincerity captured the attention of many classmates, especially the girls. Despite his popularity, Haruto’s heart held a special place reserved only for Miyu.

One ordinary school day, Haruto spotted Miyu walking down a crowded corridor. Her face was familiar, yet she passed by without any sign of recognition. It was as if the years had erased the memories she once shared with him. Haruto felt a surge of emotions but chose patience over pressure. He decided to rebuild their friendship gently.

Slowly, Haruto started spending time with Miyu again, sharing simple joys—laughing over jokes, confiding in each other, and rediscovering the comfort of their past under the willow tree. Miyu found herself drawn to Haruto’s genuine kindness but didn’t realize her heart was beginning to beat for him once more. Meanwhile, Haruto quietly treasured the chance to relive the friendship he had always dreamed of.

However, the closer they grew, the more Miyu hesitated. When she learned of Haruto’s popularity, her insecurities crept in. Maybe she was just one among many admirers now. To hide her vulnerability, she pulled away, leaving Haruto confused and longing to understand why she was becoming distant.
