On Royals? ML obsessed with MC/Screwed in the head? Rich×Ordinary? Master×Servant? Uke being the caregiver of seme or meeting the prince as a child? It would helpful if you were more specific. Anyway, here's some mangas I can suggest -

Exceed 1
Can't remember title -
Uke involuntary travels to an alternative universe where he is a prince's lookalike. The Prince find him and uses him as a decoy to stay in the palace in his place while he sneaks out. A neighbouring kingdom's king/prince visits the castle during one of those times and falls in love with uke. When they're swapped back the king doesn’t feel the same charms although they have the same face. The king has to leave but he offered the prince's sickly father to spend a few nights with the prince in exchange of some economical and political benefits. The uke agrees to be the one to sleep with the prince. Shortly after that a the castle is attacked and the OG prince d!es while the uke is on the run with the OG prince's younger brother to save him and help him ascend the throne later, lile promised. Seme finds the og prince's de*d body and later uke while he was laying low which confirmed the King of the uke's existence.
