July Park is a man caught between two worlds—his present and his mother’s past. Armed with a mysterious time-traveling watch, July is thrust into pivotal moments in his family’s history, witnessing firsthand the choices and tragedies that shaped their lives. As he unravels the layers of his mother’s untold struggles and regrets, July discovers the haunting truth: his presence in the past isn’t accidental, and his actions carry devastating consequences.

Driven by love and a desire to ease his mother’s pain, July makes a life-altering decision to change her past, giving her the chance to escape hardship and find happiness. But this act of selflessness comes at a steep cost. By rewriting her story, he unwittingly erases his own existence, unraveling the very fabric of his life.

As July fades from the future, he’s forced to confront the life he could have lived—the love, the children, the dreams now lost forever. In his final moments, July comes to understand that while we cannot control the past, we can choose how we impact the lives of those we love, even if it means sacrificing everything.
