Looking for a manhwa similar to the artwork of https://www.mangaupdates.com/series/sme289g/there-s-no-use-hanging-on
The manhwa I'm looking for the FL has blonde hair too. The FL finds out she's the villain of the story the prince I think he is (turns out the prince is her biological brother) and her suppose dad is the father of the villain girl the prince is in love with . Her mom turned out to be the queen but died when she was little and the dad she grew up with isn't her biological dad the king is. that's all I remember
