Su Que was born in the Su family, but does not belong to the Su family. His father's suicide note was like a well-arranged bet, pushing him deep into the family secret room - where the Su family's sins and atonement from a hundred years ago were hidden. He must solve a mystery that three generations have not dared to face in seven nights, and the stakes are the fate of the whole family. Every old letter, every secret message, is a gap in time, reflecting the shadow behind the family's glory. Su Que's motivation is not only to seek truth, but also to redeem himself: only by uncovering the truth can he prove that his existence is not just a matter of blood. The story unfolds in the deep ancestral home and the wasteland of memory. The family's love, hate, life and death are reshuffled in the hands of Su Que. Who is the real player in this gamble? Who can find a home among the ruins?
