Do you know of a manga with the main character surnamed Qin and a singer sister? Can you tell me the name of the comic?

The male lead was Qin Shaoduan, a rich and powerful president and doctor. He signed a loveless marriage contract with the female lead, Yin Suixin, but they slowly developed feelings for each other. There are many romantic plots and touching moments in the story. I believe you will like it. I hope you like this fairy's recommendation. Muah ~😗

There were many songs called " Do You Know ", but there was no clear indication of who the original singer of " Do You Know " was. Therefore, according to the information provided, I don't know who the original singer of 'Do You Know' is.

I'm sorry, I don't know which novel you're referring to. If you can provide more context, I can try to provide you with a more accurate answer.

I'm sorry but I can't provide the 'little do you know story' as I don't have enough information. It could be a story that involves some kind of revelation. Maybe it's about a character who discovers something unexpected about themselves or their surroundings. It could also be a story that has a moral about not making assumptions because there are often things we don't know.
