Shen Tang, the heir to No. 7 at the entrance of an alley in Wangxi Town, was tricked in her previous life by Lin Qiuyue, the owner of the guesthouse at No. 9. Out of kindness, Shen Tang agreed to receive a cash-on-delivery package for her neighbor. However, Lin Qiuyue used Shen Tang's address to maliciously return orders and take local specialties without paying. As a result, Shen Tang was held accountable by suppliers, had her bank account frozen, was forced to resign from her operations job and sell her courtyard, and even depleted her parents' savings. She eventually collapsed during an official meeting. Reborn on the very day Lin Qiuyue came to collect another package, Shen Tang immediately registered her courtyard as a short-stay guesthouse overnight. Armed with guest registration records, surveillance footage, and official penalty notices, she confronts Lin Qiuyue's blame-shifting schemes and a malicious influencer's staged photographs. By standing firm on the rules, Shen Tang gradually reclaims the peaceful life she deserves.
