"Like" in which aspect?

Try Harlequin mangas, there are tags for them, they are josei. Theres always marriage, misunderstanding and love at the end
In aspects like that the seme misundetstands the uke, and that he rapes him, but then he regrets it, because he actually likes him. I loved everything in this manga!!!
Harlequin is the name of the mangaka or the manga series?
I think they are published in a magazine called Harlequin, im not sure

Mangas that are very similar to The Royal Fiancé? It could be shoujo to. I really like the story of it, so if someone knows similar storyes, please tell me.
