I don't read much of that genre but Villains are destined to die is one of the first ones I've read and I love it so much the art is soo beautiful. Tho not finished reading I found Villainess is a marionette and Roxana super interesting as well. What can I say I love my strong women and beautiful artstyle!
as someone who only started reading them during the pandemic, imo (these are all rofan, btw):
1. who made me a princess
2. why raeliana ended up at the duke's mansion
3. doctor elise
these were the "must reads" that everyone was talking about (on twt, at least). they were like a rite of passage almost haha
what do you think the big 3 for isekai/historical manhwa are? i am SO curious as someone whos read ‘lots of them
