Qin Yifan is the Qin family's only male heir, with seven sisters renowned across various fields: a corporate CEO, a famous doctor, a legal queen, a top film empress, a security chief, a state banquet chef, and an elite university PhD holder. Yet, he is willingly setting up a street stall under the overpass to apply screen protectors, treated by his family as good-for-nothing. When capital titan Yue Zhengrong joins forces with insider Wen Lan and white-glove He Feng to launch the 'Seven-Star Broken Chain' total offensive against the Qin family, the seven sisters fall one after another, pushing the Qin family to the edge of a cliff. At this life-or-death moment, Qin Yifan is forced to tear off his disguise and strike fiercely, leaving the family shocked to realize that the younger brother they had protected behind their backs and despised for over a dozen years is actually the man standing at the top of the capital food chain.
