Defying Kurosaki-kun Vol. 11 (Kodansha, 2019)

Yu and Kurosaki-kun have started going out-on the condition that she “learns to obey him.” Brought down by her new boyfriend's no-holds-barred training, Yu is, for once, doing as she's told. When she stops clashing with Kurosaki-kun, she sees a new side of him, and just in time for their first Valentine's Day to arrive. Yu is nervous, but come on, even crabby Kurosaki-kun has to accept chocolate from his girlfriend! If she can force her way through the crowds of the princes' admirers to get it to him, anyway… Will Yu's Valentine's Day turn out to be sweet, or bitter? Plus, a new school year will be bringing changes to the dorm, too…
