Have you tried chinese historicals? I had and still have a lot of issue getting into Korean sageuks. I don’t know why because historicals were never sth I avoided. But c dramas changed it for me because a few of them aren’t that different from people wearing costumes. That’s how the romance of tiger and rose is too, infact the premise is also that a writer gets into her script and realizes that she has become a character that has to die very early on, in the script. I haven’t spoiled it because it’s literally the first episode. But the show is such a hoot and hardly ever is it bothersome that it isn’t set in mordern times. But I know that you’ve tried before so this may not work for you. I hope ot does though, because it’s a good, fluff fun, short watch.

Also adding sth which might intrigue you is that the show is set in a matriachal society. Honestly this was the nost interesting part for me which made me stay too. How they’ve basically reversed and imagined how a world under women rulers could be and how that clashes with the traditional setup. But that’s nothing serious either, it’s all just fun.
