Intelligent, avenging FL that’s always 2 steps ahead?

Hello! I’m looking for recs for historical/costume dramas with a revenge-seeking, extremely intelligent FL that’s always 2 steps ahead and shows next to no weakness. I’d love ML to be supportive and not overbearing in trying to protect FL. Im okay with enemies-to-lovers and subtle romance like in The Double. Ideally a drama with under 40 episodes lol I’m really enjoying rebirth/faked death plots. HEA only please! I can’t do sad

dramas I’ve watched and LOVED: The Double (my absolute fave!!!) Blossom Threads of Destiny Are You The One (I didn’t finish this yet, it’s dragging a bit and I’m scared of the reveal lol) Legend of the Female General
