My Wife Didn't Know the Heart Transplant She Performed for Her First Love Was Mine

Everyone knew Lily only married me to spite her first love.

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

Later, when her first love returned to the country due to illness, Lily took meticulous care of him. She even warned me repeatedly:

"Ethan's heart condition is fragile. If you dare show your face around him, you'll have hell to pay!"

Finally, when she brought up divorce for the hundredth time, I agreed.
