在这部有爱一家人片中,这是一部描述“幸福居”民宿三个女儿与一位长工的故事。在剧中，万圣仁（宥胜 饰）的妈妈以家规规定30岁前必须结婚，逼他相亲尽快成家，但圣仁对小时候给他温暖的小天使却念念不忘，然而线索只有一条手帕。这时刚好看到新闻正在报道“幸福居”民宿，招牌图案跟手帕上的图案一模一样，于是圣仁去应征长工，认识了有爱（房思瑜 饰）三姐妹。
What will a young man do when his mother has an inflexible rule that all of her children must marry before the age of 30? Wan Sheng-Jen (Chris Wang) faces the wrath of his mother if he doesn't meet her marriage deadline. As a result, he is determined to find a "little angel" from his childhood, but he doesn't know the girl's name or any other information that could help track her down.
