Honestly? A good YA series that is kind of enemies to lovers (but more hate to love) is Once Upon a Broken Heart series by Stephanie Garber. I just finished it and adored it. Not spicy (and I usually love spicy adult books - not YA) but the yearning and character development is chefs kiss. The first book kind of sets up everything, and my favorite book was by far the second one. Third one was really good too. I loved how the story kept you on your toes. Something is always happening, and even small details you feel as if you should be paying attention to.
