Seven-Day Reincarnation, the Deal with the Devil

In order to raise the medical expenses of his sister Su Yanning, Su Yanwei reached a "seven-day deal" with the mysterious man Shen Shiyan. She didn't know that Shen Shiyan had been trapped in a seven-day reincarnation cycle for a hundred years - due to his obsession with Mingchun Theater in the Republic of China, he repeatedly experienced separation and tragedy, and the lotus mark on his wrist was a symbol of curse. During the transaction, Su Yanwei gradually noticed anomalies: her sister mentioned "Tuberculosis" that her grandmother loved to listen to, and the changes in ancient books in the bookstore were all related to Shen Shiyan's past. Although Shen Shiyan is cold, he always protects her at critical moments. The two of them move from wariness to trust and explore the root of reincarnation together. The greedy Zhao Chengze coveted the secrets of time and space in ancient books and tried to snatch "The Secret Records of Mingchun Theater" to tamper with history for profit. In the bookstore, he forcibly triggered the secret technique, causing black time and space turbulence. At the critical moment, the red light of the ancient book resonated with Shen Shiyan's reincarnation mark, pulling away the power of a century-old curse. The mark disappeared with the golden light. Shen Shiyan was finally free, and Zhao Chengze was swallowed by the turbulent currents. In the end, Su Yanning recovered, and Su Yanwei and Shen Shiyan broke the shackles of reincarnation. The three of them bathed in the sunshine in the park, and the regrets of the past were replaced by the warmth of new life. The implicit agreement of "opening a bookstore and sharing peace" a hundred years ago was fulfilled in a new way, confirming the theme of "the best ending is to cherish the present".
