Found Their Records, Ended the Marriage

From the back cover

Lily finds an old phone in her husband Ethan Lloyd's coat pocket, unlocked with his first love's birthday. Inside are records of every encounter he had with Claire Bennett — in his office, in a café bathroom, even in their marital bedroom. When she calmly asks for a divorce, Ethan smashes the phone and dismisses it as the past, promising a Hokkaido ski trip he has postponed for years.

Lily has spent five years as his second choice, always waiting alone at theaters and in the rain while Claire's presence lingers in his music account, his old social media, and the art he chooses. At a café, she asks her lawyer friend to draft a divorce agreement, and her friend warns her that Ethan never cleared his heart.

When Ethan drives past with Claire in the passenger seat, he coldly assumes Lily twisted her ankle to get his attention. She tells him she doesn't need him to survive, and though he carries her inside and tends her ankle, his indifference remains — a slap followed by a piece of candy.
