After Exchanging with Her, I Succeeded in My Revenge1
My younger sister, Lily Moran, in her quest to marry into a wealthy family, was willing to sacrifice herself for the CEO.
The CEO's beloved, who was gravely ill, needed blood, liver, and eventually even a kidney. Lily donated all of these to her.
As an emergency doctor, I saved Lily countless times, but due to leaving scars from her injuries, she ended up killing me in a fit of rage.
When I opened my eyes again, I found myself back on the day Lily met the CEO.
Excitedly, Lily announced to the whole family, "Mr. Zuniga asked for my contact information. He's interested in me."
This time, instead of advising her against it, I clapped and smiled, "That's great. You'll soon be marrying into a wealthy family."
...
While donating blood at the university blood drive, Lily was discovered to have a rare type of blood known as "panda blood."
The CEO of Zuniga Group, Cole Zuniga, chased after the blood drive to ask for her contact details.
Lily fell for Cole at first sight, believing that she was chosen by the CEO and that she was about to marry into a wealthy family.
Little did she know, Cole saw her only as a blood donor, to save his dying beloved.
