[Multi SUB] ｜一个送快递的穷小子，一天突然收到记录父亲一生的日记本，鬼使神差下高语浓在日记本中写下批注，给予父亲超越时代的商业建议！！#下山追短剧#MiniDrama#精彩大陆短剧

The protagonist finds his father's diary, which details his struggles. By adding annotations, he discovers he can alter his father's past choices, turning a bankruptcy into an opportunity to open a successful internet cafe and avoid a previous injury.

The changes lead to the internet cafe's rapid success. However, a friend named Zhang Shunfa, who previously scammed his father, reappears, threatening their new prosperity. The diary can only be edited once every seven days, making careful interventions crucial.

The protagonist guides his father to invest in prime locations and connect with key figures like Chen Dong. Despite growing wealth, family members, including his aunt and uncle, show animosity and attempt to undermine their businesses, leading to conflicts and police intervention.

The father uses connections, notably Zhao Guang, to resolve business disputes. The family's burgeoning wealth allows the protagonist to flaunt his success, leading to confrontations with envious classmates and relatives. The aunt's family continues to create problems, prompting the protagonist to offer new business strategies for his father.

The family relocates to Kyoto, where their internet cafe and mala tang businesses thrive. However, the aunt's family follows, stealing their recipes and initiating a price war. The protagonist navigates complex relationships, including a blind date with Jia Wenwen and encounters with past acquaintances, as he works to protect his family's interests.

The family's property and company in Kyoto are revealed, showcasing their growing empire. During a business meeting, the protagonist unexpectedly reunites with Chen Xuening, his childhood crush and ex-girlfriend, who is now a project manager at Green Mountain Investment. Their past complicates investment discussions as his aunt's family, backed by Chen Xuening's brother, attempts to acquire the family business at a low price.

The protagonist confronts Chen Xuening about their past, leading to emotional revelations. He apologizes for neglecting her and admits to past mistakes. Despite the unresolved tension, they find themselves working together against common adversaries.

The秦 Group, led by Qin Chuan, attempts to undermine the family's businesses. The protagonist orchestrates a multi-front attack, using patent infringement lawsuits, alliances to terminate leases, and media exposure to dismantle the Qin family's empire. His father, seeing their victory, announces his retirement, much to the protagonist's reluctance to take over the family businesses.
