In the glittering world of Formula 1, where every second matters and reputations are everything, Ferrari's rising star Lingling Kwong is untouchable-on the track and off. But when she meets sharp-tongued motorsport journalist Orm Kornnaphat during a high-stakes race weekend in Singapore, the lines between professional and personal begin to blur. Set against roaring engines, flashing cameras, and smoky jazz bars, "Lines We Shouldn't Cross" is a slow-burn romance crackling with tension, desire, and the dangerous thrill of wanting something-or someone-you shouldn't. Sometimes, the most unforgettable stories are the ones you never planned to write.
