Plot

When Mook, a single mom with five girls, and Tum, a widower with two kids, want to get married, both families agree to move in together for a year with a condition that if any family member is unhappy, their marriage will be off.

Mook is a single mother who is still young at heart. For ten years, she has been living with her five daughters. One day, Mook falls in love with Tum, a kind-hearted widower with two young children. They fall madly in love and decide to get married. However, things do not go as smoothly as planned and Mook's children express that they are not okay with her decision, especially Petch, who has been through thick and thin with her for the longest time. Petch does not want to see her mother's life ruined because of another failed relationship. Meanwhile, Boom, Tum's son, is for the marriage as he wants his father to find happiness. Mook and Tum want to be together but are not sure if their children will get along or not. Therefore, the two families make a deal to move in together with the condition that after one year, if any family member is unhappy with the arrangement, Mook and Tum's marriage will not go ahead. When the family, that had until now been full of girls, is intruded by new housemates, chaos arises. They have to deal with big adjustments, conflicts, resentments, and romantic relationships that form between two soon-to-be step-siblings. Let's see if the two families will last ONE YEAR.
