1. The Heir & The Investigator: The 'Accidental' Fiança (Idea #1)Logline: A ruthless tech billionaire, whose company is under investigation for corporate espionage, is forced to hire the fiercely ethical forensic auditor who openly despises him, leading to a secret, high-security romance that threatens both their careers and his family legacy.The Conflict (Enemies to Lovers)• He: Julian Thorne, CEO of a global defense tech conglomerate. Known for being cold, untouchable, and aggressively private. He believes everyone has a price and efficiency trumps emotion.• She: Dr. Clara Vance, a brilliant, no-nonsense forensic financial auditor. She suspects Julian's company is cooking the books and actively testified against his practices in a prior case. She views him as the embodiment of everything corrupt.• The Catalyst: Julian’s controlling family forces him to enter a high-profile, short-term engagement to a "stable partner" (Clara) to mitigate public panic and secure a crucial government contract. If she refuses, her small, pro-bono auditing firm will be buried under legal fees by his team. She agrees, viewing it as an undercover chance to finally expose him.The Secret (Hate to Secret Romance)• The Hidden Connection: While publicly fighting over corporate ethics, they find they share a surprisingly dark, dry sense of humor and a mutual, intense obsession with solving complex puzzles (e.g., vintage war codes or forgotten languages). Their secret meetings for "puzzle night" quickly spiral into explosive, secret hookups, driven purely by physical chemistry and a shared intellectual spark they can't find with anyone else.• The Stakes: If their genuine attraction and secret meetings are exposed, Julian loses his company (due to the breach of his "stable" public image) and Clara loses her career (as it proves her testimony against him was biased). They must maintain the facade of a bitterly unhappy engaged couple while hiding a passionate, emotionally resonant affair.
