在音乐教师顾家源和新婚妻子谷慧庭的快乐二人世界中, sudden arrival of five children disrupts their tranquility. It turns out, these unexpected guests are the orphans of Amusingly referred to as his siblings, left under his care after the untimely demise of his sister and her spouse. To soothe their hearts, Amusingly pretends their father is in distant Africa practicing medicine. In order to provide a stable environment for the children, he sacrifices his teaching job for a less demanding one as a music teacher at an academy. With two families of seven people living under one roof, the ensuing friction and the challenges of nurturing the children paint a heartwarming picture of family life.
