A serious relationship unfolding between a daughter and her father as their family falls apart. Mai (pseudonym) has lived alone with her father since childhood, but as she grows older, she increasingly loses her smile. She stops attending school regularly, and her bond with her father gradually weakens. As a result, she begins exhibiting violent behavior, and fearing the complete collapse of their household, her father ultimately seeks help from a "hikikomori independence support center." This documentary realistically portrays how the parent-child relationship deteriorated and what eventually transpired. [Thanks to everyone for supporting KMP's 20th anniversary!!]
