After He Zhiyuan secures a major account, he treats eight colleagues to seafood to celebrate. Fang Yun secretly spreads word that guests can be brought along, and three tables of friends and relatives show up uninvited, inflating the bill from 3,860 yuan to 23,688 yuan, all charged to He's name. He pays only for the main table and refuses to foot the bill for strangers. Fang Yun misappropriates his work badge and fabricates chat screenshots to disguise the personal banquet as corporate hospitality, and even goes to the hospital to use his mother's surgery deposit to force him into withdrawing his evidence. The investigation implicates Deputy Manager Qiu Ming, who remotely opened permissions, deleted attachments, forged expense reports, and replaced client files. Relying on surveillance, recordings, and version histories, He Zhiyuan proves his innocence, and the client restores the project acceptance. In the end, Fang Yun is fired, Qiu Ming is investigated, and his mother's surgery proceeds smoothly.
