(read premise) Cin Seville flies to London to learn how to swim for her sister’s poolside wedding. She doesn’t expect the man in the opposite room. For one month, they share late-night hallway conversations, swimming lessons, and a rule that makes everything easier: no names. No promises. No future beyond thirty days. It’s safer that way. Until she leaves. Two months later, at her sister’s wedding, Cin comes face-to-face with the one person she almost let matter.
