The drama follows the lives of seven boys navigating their school years and personal growth, each grappling with family obligations, loss, poverty, abandonment, violence, and rejection.
After an unwanted return to Songju-si, Kim Hwan meets six boys. As an outsider and the son of Kim Chang Jun, the boys sometimes find him suspicious and misunderstand his actions, leading to conflicts. Despite these initial difficulties, they eventually become friends. It seemed awkward at first, but over time, they grow closer and open their hearts. They travel and play together, sharing their problems to help each other heal. Realizing they all have similar family issues, they become even closer. Hwan confronts his own feelings by staying with the other boys. As he spends time with them, he starts to like Songju-si and genuinely wishes for these days to continue forever.
However, Chang Jun notices the other boys and considers them useless, insisting that Hwan stay away from them. Hwan, who has always lived an obedient life, raises his voice for the first time and confronts his emotions.
