Ten years of perfect friendship. Thirty days of forced cohabitation. And a couch so narrow that any sudden movement constitutes an act of cold war. Sandra is a true crime podcaster whose career has stalled in the limbo of 'almost famous.' Matias is an architect obsessed with order and silence. When both lose their apartments on the same day for equally ridiculous reasons, fate doesn't smile; it gives them a knowing look and rents them a shared flat in Madrid. They set up ridiculous rules to avoid killing each other: shower schedules, labels on fridge items, and a strict prohibition on talking about their romantic failures. But Madrid, with its stifling heat, acts as a catalyst. The tension doesn't arise from hatred, but from suffocating physical proximity. Every time he passes behind her in the kitchen, the air becomes thick, charged with an electricity they both refuse to name. Can they survive adulthood without ruining the only relationship that has worked for them? A romantic comedy about the sweet terror of crossing a line you've spent years pretending doesn't exist.
