Yonoi Tsukihiko's Happy Hell Vol. 6

But that was before he met orange farm heiress Hanabata Mikan. Although the two are complete opposites, he fell hard for Mikan, and now he can't imagine a life without her. Is that the sound of wedding bells in the air? Not quite--not if Tsukihiko's father has a say in the matter! The patriarch is vehemently opposed to the union, and the reason has something to do with Mikan's mother...!
