Win Over the Dragon Emperor This Time Around, Noble Girl! - Vol. 1 Ch. 1

[Bluehammer12]

To be fair with the whole incest thing, he is royalty in a pseudo-medieval time period. That was just the norm back then.
Also to all the people bitching about age. It's a fictional story about fictional characters set in a fiction pseudo-medieval world. So either get over yourself or leave.

Aside from pedophilia.. at least this manga called out how gross incest is? I like that crown prince is portrayed as disgusting
