This was such a downer. Watching it felt like I was drowning in a syrupy pool of despair and dissatisfaction. Apparently, this was meant to be the Chinese version of Love in the Moonlight but I can categorically say that this was a rather poor facsimile. Ultimately, the Korean version is far superior in both plot and casting. The story didn't know if it wanted to be a comedy, melodrama, or serious political suspense; so it ended up being a superficial mishmash of the most common palace tropes.

A girl who grew up as a boy went into the palace to collect a debt and ended up being appointed as the King's chief eunuch except the king is a mere puppet who's controlled by both his stepmother-the Empress Dowager- and the top general. The King desires to be a good ruler but in order to do that he must unseat the Dowager's camp. Both teams thrust and parry without actually landing any major blows. In the midst of the power struggle, the King falls in love with the FL and they work together to achieve said goal.
