Group Pampering in the 1970S

After dying, Zisu unexpectedly received a gift package for newcomers from the underworld, which brought him from the new era of the 21st century to the bitter era. Just when he was about to give a negative review, he discovered that this world was actually a combination of two novels, and his brother-in-law and sister-in-law were the male and female protagonists respectively. What does this mean? It means you can win. This must be a five-star review!
