When Liam publicly announced that the sponsor's daughter would replace me as his exclusive navigator, he demoted his chief mechanic of five years to a logistics assistant. In the garage, Chloe carelessly smashed the custom-painted helmet symbolizing our startup promise. Liam only cared if the shards had scratched her hands. Without arguing, I quietly reset all his exclusive engine tuning data to factory defaults. I signed the contract with the rival F1 team, choosing to sever our ties forever. The price was turning our shared startup memories into ashes and sacrificing five years of my youth. He confidently climbed into his cockpit the next morning, oblivious that his dashcam had already exposed their long-term affair. As the championship race began, I watched closely, waiting to see his fate at the most critical corner.
