[Request] I forget a title but only know its content.

I know its brief content but do not know a title.

It's awkward to say it's a request, but let me tell you its content.

If anyone knows it, please tell me.

There are three main characters--a normal male citizen, a normal female citizen and a king.
(he could be a landlord or prince but it's sure that he's in a high rank)
The male citizen and the female citizen has loved each other.

While a king is parading in a certain town, other town main characters comes to watch
the parade, bowing their heads down on the ground.

However, the king spotted the female character and took her into his palace to make her
his concubine.

In the end, she is completely fallen into the hand of the king, became his concubine and got
pregnant.

If my memory is right, a male citizen became a knight for protecting her.

If you can know the title from my writing, please tell me.

Thank you.
