Pampering Substitute Wife: Husband Is Too Fierce

She was engaged to him on behalf of her sister. She thought she was marrying a man who was notorious for suffering from serious diseases. Unexpectedly, he was shockingly handsome, with good physical strength and a good figure. Not only that, he also doted on her in every possible way, spending money on her and giving her cards, and she abused her and gave her advice. In front of people, he was a ruthless heir to the empire, but behind people, he was a candy that entangled her in the bed and wouldn't let go. After the marriage, he specially bought an uninhabited island for their honeymoon. She rubbed her sore waist and tried to escape, but he easily caught her and put her on the bed. Then she heard the man's bewitching voice: "Good boy, I promised my son that I will bring him a sister when I go back."
