[Urban workplace + business suspense + tech industry rivalry + protagonist proving his innocence + twists and counterattacks] On the eve of a presentation for a hundred-million-yuan project, Cheng Yan discovers that his competitor’s proposal is identical to his own internal draft, right down to an erroneous parameter he had already deleted. Yet the download history, sent emails, surveillance footage, and recordings all point to him. The company gives him one night: resign voluntarily, or they call the police. Everyone is waiting for him to confess, but Cheng Yan realizes that the evidence chain is so airtight it looks like an answer written in advance. If the old evidence can be fabricated, he’ll create a new proposal that only the mole could get their hands on. Whoever uses it tomorrow will prove his innocence for him!
