My Wife Doesn't Know the Heart She Transplanted into Her Rival Was Mine

Everyone knew Lily only married me to spite Jack, her idealized ex-lover.

For five years of marriage, she played the role of a caring wife and renowned cardiologist in public. But behind closed doors, she was cold as ice towards me and brought up divorce countless times.

Later, when Jack returned to the country due to illness, Lily tirelessly cared for him. She even warned me repeatedly: "Jack's heart is weak. If you dare show your face around him, you'll regret it!"

Finally, on the hundredth time she mentioned divorce, I agreed.
