Konna Kawaii Iinazuke ga Iru no ni, Hoka no Ko ga Suki na no?

Kouta is a cash-strapped high school student who spends his days working part-time jobs just to get by. His life is turned upside down when Chris, a dazzling celebrity and stunningly beautiful girl, suddenly appears before him and declares herself his fiancee. The shocking truth is that ten years earlier, Kouta's money-hungry father arranged a marriage contract without Kouta's consent. Refusing to be controlled by their parents, Kouta and Chris quickly agree to join forces as an "Engagement Breakup Alliance" and annul the unwanted arrangement. Yet Chris has an ulterior motive. Her real goal is to win over Kouta, her first love. To that end, she advises him to fabricate another fiancee, beginning with finding someone he actually likes. Kouta promptly rejects the idea: there is no need, since he can simply propose to the girlfriend he already has. Chris is left reeling—"A girlfriend?!"—and the revelation ignites a love triangle set in motion by the very cancellation of an engagement.
