Today's mothers of two children feel sad and helpless. Four families have parents to help them and have no parents to help them raise their children for a day, as well as trivial matters. Four groups of families, two situations, record a day filled with milk stains, homework, and crying for mothers: it is the embarrassment when running to the hospital alone with the baby, the moment of respite when someone comes to help, and even more, in the identity of "mother", the sadness that cannot be hidden, the helplessness that cannot be escaped, and the tiny glimmer of finding oneself in the cracks.
