My parents died in an accident leaving behind only huge debts, and when I became an adult, I was a poor little girl who was doomed to die of the disease. That’s me, “Laria”. The dark side of this manhwa, Duke Icard, took me in as a daughter-in-law in order to deceive the eyes of the restraining forces, so let’s secretly collect money and seize the opportunity and run away! I found a way to cure the disease, and the funds for escape are slowly coming …
“If you die, I will die with you unconditionally. I can’t live in a world without you.” …husband? Why are you so obsessed with me?! Wasn’t he cold-blooded who didn’t love anyone? And, Father, I must be a loser. Why are you suddenly trying to save me?!
Somehow the world doesn’t seem to work the way I knew it.
