Defying Kurosaki-kun Vol. 13 (Kodansha, 2019)

While Kurosaki-kun's junior, Hino-kun, works from the shadows to isolate the now-popular prince from his friends and admirers, Yu remains blissfully unaware. The biggest thing on her mind is how far to take her relationship with her boyfriend! These days, the (former?) Black Devil seems sweeter and sweeter to her-and she doesn't know how to handle it! She wants to connect on a deeper level, but when she and Kurosaki-kun end up in a fight instead, could it be that the unlikely couple is simply incompatible? But in the background, Hino-kun's plans continue to escalate… Includes a bonus story starring Mina!
