When My Wife Became a Surrogate for Her Cancer-Stricken Lover: I Walked Away

Ethan has spent twenty years in the Pei household as the adopted son Grandpa Pei took in from an orphanage, and five years married to Zoe Pei, the heiress of Pei Group. Their marriage has always been one in name only, because Zoe's heart belongs to Leo, her first love from her teenage years. When Leo reappears, stricken with cancer, Zoe devotes herself to him entirely, leaving Ethan invisible in his own home.

Ethan has been hiding a diagnosis of bone cancer for six months, enduring chemotherapy alone while Zoe spends her days at Leo's hospital bedside. On their wedding anniversary, he waits with dinner and cake until dawn, but she never comes home. Instead, Leo sends him a photo of himself embracing Zoe, and later announces that Zoe is carrying a child for him.

Ethan leaves a divorce agreement and the house keys on the dining table and walks away without looking back. Half a month later, he meets Zoe and Leo at the hospital, where she demands to know why he is divorcing her, and the doctor warns that his time is running out.
