SMAB with greek myth background like the Percy Jackson series and romantic development like Circe or Song of Achilles.

I'm looking for a romance novel based on Greek mythological settings. Human/Greek God/Mythical creatures/figures are all good. I enjoy books with fantasy adventures and a romantic development with hint of humour like the Rick Riordan's Percy Jackson series. But I also really enjoyed the slow, growth, and blooming relationships from companionships in adventures like Circe and The songs of achilles by Madeline Miller. I also quite enjoyed her writing style, I find it simple but very compelling.

About contents and language: I prefer it remain adventurous and romantic. I don't mind 18+ language/scenes. However, I don't like books that put too many 'interesting' words. I really enjoyed Circe, it's simple and easy to follow. Many quotes from that book uses simple language but are powerful and poetic. I enjoyed her writing styled.
