Have you recommended an ancient novel where the female protagonist is an incense maker and always wears blue or black clothes, the male protagonist has amnesia and helps with the investigation, and the male protagonist has red hair?

The female protagonist makes incense according to the customer's request. The male protagonist comes to the place where the female protagonist is to investigate. The male protagonist's memory is sealed by his grandfather or elder, so he doesn't know the female protagonist. The boss of the female protagonist's street asked the female protagonist to help the male protagonist investigate. The male protagonist in the ancient language seems to have red hair. The female protagonist likes to wear blue because the male protagonist always wears blue clothes.

Answer 1

I think that the book,'Tonight and Tomorrow' might meet your needs. The female lead was the princess of the dragon race. She knew how to make incense and liked to wear blue and black clothes. The male lead was the young lord of the Dragon Clan. He had lost his memory when he came to investigate the case and had red hair. I hope you like my recommendation. Muah ~
