Clara and Leo notice each other daily on the commuter train, exchanging glances and polite smiles but never speaking. A small accident—spilled coffee or a dropped notebook—forces them to interact. Initial awkward conversation slowly grows into shared laughs, casual coffee runs, and small moments of vulnerability. Misunderstandings and missed connections create tension, but their encounters build attraction. A major train disruption strands them together, forcing hours of conversation and bonding. Through shared experiences, mutual admiration and attraction grow, culminating in their decision to meet outside the train and explore a deeper connection.
