Ordinary office worker Yoshinomiya (Masaji Fukuyama) and his wife Nomomiya Green (Ono Machiko) have been married for many years, and they are very close to each other. They jointly raise their clever and clever son, Yoshinomiya Keido (Keido Ermiong). Happiness is revealed everywhere in the tranquility of life. To the surprise of the trio who had thought that a peaceful life would last, a phone call from the hospital where Gyeongdo was born dragged the small family into the top of the wind and waves. It turns out that Qingdo is not the son of many and green, but the crystallization of love between Saiki Xiongda (Lilly Frank) and Yugali (Yoko Makagi). Is the feeling of getting along with each other precious, or is it important that the fetters are connected by blood? In the face of the consequences of a small misunderstanding many years ago, many and green do not know where to go. For Xiongda, Eucalyptus and their non-biological children, Saimu Liuqing (Huang Shengxuan), they are also standing in front of the crossroads of life.
