Since you have been kind to me, I will repay you!
The three stories are all about repaying a favor.
Mingshu, you have taken a good rest for the past three years. After three years, I will give you a peaceful mansion.
Mr. Han, if she doesn't like you, I will make her like you. You have no money, let me help you make money.
Do you want to dominate the country? I will try my best to help you, but whether it succeeds or not, you have to let me go.
