My Vow to My Liege (2020)

FuChai rules as the King of Ng while concealing that she is a woman, putting public responsibility at the centre of every intimate choice. Enemies, a minister and a guard belong to a political world with loyalties that cannot simply be set aside for a date. The Steam edition has English text and Chinese voice acting. Choose it for fantasy-inflected ancient Chinese court drama, with war, betrayal and a significant age difference in one relationship.
