He wanted to think of a way to make him guard him for the rest of his life…He didn’t expect that there would be such a thing as "love" in the world!

In order to save his younger brother who had accidentally injured the Fourth Young Master and was imprisoned, he humbly entered the mansion and begged the Twelfth Young Master to help him.

He was a doctor, so this was a piece of cake for him…
