You probably already know of it but Under the Oak Tree and A Lady's Guide to Survival are both excellent. (Idk that the second one is on mangago though). The first one has 18 chapters so far and they're long...the female lead is really timid but has trauma and determination, not annoyingly shy. The female lead in the second one is so badass I love her omg-- 10/10 would reccommend, lots of intrigue in the second one, not immediately clear who the love interest will end up being.
