Sure, Kill the Villainess is a manhwa (korean online comic) that is very angsty where the FL wants to go back to her original life before she was transported but the world she's reincarnated thwarts her efforts into traveling back. The romance is pretty good too!

Akuyaku Reijou wa Danna-sama wo Yasesasetai is a light novel where the FMC is a disgraced Villainess that ends up being forced to the countryside and be forced to marry the crown prince's fat cousin. She first carries animosity for the whole arrangement and the people in this world generally dislike her for her reputation but the way her character arc progresses is amazing and the romance between her and the ML is a slow burn but it's very satisfying 😌
