Book recs based off of Turkish drama

So I'm watching this Turkish drama vatanim sensin and the second couple ( Leon and halil) have so much chemistry it's insane. The story is basically that she's a Turkish girl who fights for turkeys freedom during greeces occupation and leon is a Greek soldier who has taken over turkey. They at first don't have too many convos but over time they go from being ENEMIES to lovers and it's this whole thing where she shoots him when he and her brother are fighting and when he wakes up he gives her this long love letter detailing how in love he is with her and all that ( keep in mind he's had this letter in his pocket to give her for a long while). It's a big argument throughout the series that no one wants them to be together and every time something terrible happens, they push through it. At one point they get married in secret and don't tell anyone. Overall, he's like OBSESSED with her and loves her so so deeply that within the first 10 episodes he's like showing how nervous he gets around her and hes always kissing her forehead and they're just a very IN LOVE type of couple. I don't know if I'm explaining this accurately enough so feel free to search up their ship name ( Hileon) or the name of the show to get the full picture on TikTok. I'll try to include links to videos but feel free to do your own research. Anyway, I really really need a book recommendation that is like pretty similar to this that isn't fantasy. I've already read the shatter me series and I feel like that's pretty similar imo but I need more romance and less fantasy if you know what I mean. Please lemme know if you guys know of anything!!
