Secrets by the Pillow

During a business trip, Xu Shao receives a high electricity bill and rushes home to investigate, suspecting Lin QiQi of cheating but repeatedly fooled by her clever cover-ups. After doubting himself, he identifies the third party using a blurry photo, gathers evidence from her phone, and proves her infidelity, leading to a divorce proposal. Despite Lin QiQi's threats and regret, she disappears on the day of signing the agreement, leaving the divorce unfinished. Five years later, after Xu Shao succeeds in his startup and plans to reconcile with his former boss, Lin QiQi returns with their child to fight over the inheritance. Drawing on past-life experience, Xu Shao discovers the child's biological father, exposes the scam, and finally reunites with his former boss.
