I know you mention that you haven't read the novel for the Villianess Lives Twice, but if you ever feel like it, here's a recommendation for the novel! The comic was amazing and I thought the novel couldn't possibly surpass it, but the original was miraculously even better (in part due to a fantastic translator). It manages to convey a lot of the behind the scenes political strategy in a much clearer fashion and you really get a sense of the depth of chess-playing the MC is doing.

Also thank you for this list! <3 I'd also recommend The Lady and the Beast (premise is a bit wtf but execution is top-class, reminds me of Adonis a bit) and the Vengeful White Cat, if you haven't already read either. Seems like they'd both be up your alley looking at your other reads.
