Looking for novels with an ambitious selfish female lead who makes use of the ML who likes her to acheive her goals, ML who is in love with her is ready to do anything for her. Not really looking for a normal couple novel with "strong" female lead who's actually a doormat with a so called over bearing dude who treats her like a maid.
I have a list: https://www.novelupdates.com/viewlist/53248/?ft=yes. Also, I have to mention Dreamer in the Spring Boudoir. The ML is devoted in the second half, but in the first half he is not the ML. It's an enemies to lovers story. And it is a tearjerker. Nevertheless, it's good. See my review if you want to know where to skip. Spring Banquet is another one. Same author. Not a tragedy. ML isn't a douche. He thinks the MC is pregnant with another guy's baby but loves her anyway. It's really his. Both of these fit your requirements really well, as they are very ambitious scheming women. You might like the Gilded Cage because it's very different. She's married to the Crown Prince but becomes the emperor's mistress to get revenge for her family. https://www.novelupdates.com/series/the-gilded-cage/
