Synopsis: More than twenty years after a tragic day changed everything, Nazuna writes a letter to a boy she once loved in silence — a devoted young boxer she used to see on the same train as a teenager. When the letter reaches his father, Ryuji, it reveals memories and emotions he never knew his son carried, prompting a quiet exchange between two strangers united by loss. Through their correspondence, forgotten truths resurface, and the act of writing becomes a way to face the past, preserve love, and spark an unexpected miracle. [© Far East Films]
