Olivia, 21, gets dumped when Lucas claims his adoptive father disapproves of her. Drunk and desperate to win him back, she knocks on the wrong door—and spends the night with Dylan Hill, the 32-year-old CEO. Lucas moves on within days, but Dylan keeps appearing: at her internship, at her hospital bedside, between her and every bad date. He's cold, controlled, and impossible to read—until he isn't. From one wrong door to a ring in Florida, this is the love story her ex will never forgive.
