I Can't Afford to Wait Too Long for Menstruation.

Lin Wan and Cheng Yan were childhood sweethearts. They broke up due to a misunderstanding when they were seventeen years old. He went overseas and she stayed in her old city. Ten years later, Lin Wan became a well-known restorer of ancient buildings. When he was repairing a century-old house, he accidentally discovered that Cheng Yan was the mysterious investor behind the project. Reunion does not have the warmth of reunion after a long absence, only tit-for-tat temptation and forbearance. As the restoration project progresses, the dust-laden secrets deep in the old house gradually surface. The truth about Lin Wan's mother's mysterious death that year is inextricably linked to the Cheng family. The two were repeatedly pulled in the whirlpool of truth and emotion, old scars were uncovered layer by layer, and new bonds quietly grew among the ruins. Lin Wan discovered that Cheng Yan's silence for ten years was not indifference, but guarding her in another way; and Cheng Yan finally understood that some waiting will always just stay in place if you don't have the courage to take that step. When the old house comes back to life, can they rebuild each other's lives on the ruins of time? This is a story about loss, reconciliation and self-redemption. Time cannot afford to wait too long, but the light that has not been extinguished during the waiting will eventually illuminate the way home.
