I think it is >Wagamama na Jewel (ch. 2 and 2.3)
Black-haired doesn't match with the description but everything else does.

Thank you very much <3
I'm looking for manga where young prince is supposed to mary a beautiful black-haired princess and he finds out that she is a boy with whom he played by the river (or lake). He has to pretend to be a girl because of some curs or something.
