An older man and an older woman met through the Internet, and they started to interact with each other, forming a kind of sister-brother relationship, and then they got together by accident. In three years of bumping into each other, they had the fruit of love. As time passes, a series of family problems emerge. They have experienced a series of life tests, struggling for a house, struggling for a living, ups and downs for life, worrying about hiring a nanny, crying for taking care of children, having no choice but to live with their children becoming left-behind children, having cold wars because of quarrels, running away because of bickering, living apart because of their own opinions, and so on. In other words, due to conflicts over language communication, human relationships, food culture, parenting concepts and geo-culture, the two have completely different views on money, values and life. Love gradually becomes the same thing and becomes a burden in life. The happiness index drops sharply, and eventually they part ways because they cannot pass the running-in period.
