Odore! Tsunderera - Sen no Noroi to Itotsu no Mahou

A prince is cursed by a witch with 1,000 curses and each day the curse changes to something different. The prince lives alone in a castle up on a hill with his manservant who helps him deal with the curses. The prince is in love with the manservant but the manservant keeps rejecting his advances while a little witch keeps coming over to see how the prince is suffering from the curses. (It's a love triangle but the prince only cares about the servant). Description by LuffyNoTomo
