Was the male lead of this transmigration novel wearing a mask?

The female lead's body had transmigrated to an era where she was an illusion. The male lead had worn a mask at first, but he later took it off for the female lead. He seemed to be an assassin, and there was another assassin with him. They had a good relationship. Later on, the male protagonist was injured because of the female protagonist (or fell off the cliff, forgot). When everyone thought that the male protagonist was dead, the male protagonist fought with them as the prince of another country. The female protagonist recognized him and forgot about the rest.
By the way, the male lead seemed to have a birthmark (or a jade pendant?) on his body. That country's people used this to find the male lead. The male protagonist had a mother who was against the female protagonist being with him.
The second male protagonist's original name was Hua Feihua (Hua Feihua). He and the female protagonist met in a brothel (he looked exactly like the female protagonist's boyfriend in modern times). At that time, the female protagonist was tricked into selling herself into a brothel after leaving the male protagonist. He seduced the old madam and tricked the female protagonist into selling herself. He seemed to be a rapist. In fact, his real identity was the prince of this country.
Thank you, everyone!

Answer 1

I recommend you a transmigration novel with the male protagonist wearing a mask. It's called Naruto: One Punch Town Security. The protagonist, Huang He, was transported to the Naruto World while he was wandering on the Internet. He gradually grew up through interactions with other characters. This novel did not follow Naruto's timeline. It was a derivative doujinshi novel. I hope you like my recommendation.😗
