Defying Kurosaki-kun Vol. 12 (Kodansha, 2019)

At long last, Yu can feel her relationship with Kurosaki-kun making some real progress after their Valentine's Day connection-but she's well aware that she and her bossy boyfriend are still far from on the same page, feelings-wise. Just as Yu psyches herself up to conclusively turn Kurosaki-kun's head her way, the precarious pair is split up in the new school year's class change! Even more worrying, the new transfer student-who happens to also be the prettiest girl in their grade year-has her sights set on Kurosaki-kun, and she's willing to push much harder than the Black Prince's usual fangirls. But Yu's biggest surprise might come from Kurosaki-kun himself. Does the notorious Black Devil have a sweet side…?!
