Liang Chen, the former heir to a top wealthy family in Kyoto, fell into ruin due to a conspiracy and was forced to hide his name and work as a clerk in an ordinary company. He should have kept a low profile and waited for the opportunity for revenge, but due to an accident, he was forced to take care of the two children left behind by the villain. One is a precocious and sensitive daughter, and the other is a sharp-tongued and clever son. What's even worse is that the child's mother, the man behind the ruin of his family, has become his nominal "wife".
In this absurd hidden marriage life, Liang Chen not only has to deal with the crying and rebellion of his children, but also has to deal with multiple overt and covert attacks from the wealthy family, the workplace, and the hostile forces of his "wife" identity. He always held back and looked for clues in his dad's trivial daily life. When his former enemy humiliated him with the absurd statement "You are the sixth child, my son is the one with the strongest connection", Liang Chen knew that the time had come for him to fight back. He wants to redefine "the strongest" in his own way.
