However, that engagement is a political marriage made regardless of her will. The fiancé is extremely possessive and has thoroughly eliminated any man who gets close to her; thus, no one can convey their feelings to Rinka, and those around them accept the engagement as a matter of course. One day after school, the heroine calls Guest to an empty classroom. "Please... pretend to be my boyfriend. My fiancé will never cancel this engagement unless he knows I have someone I truly love. So, I just want at least one person to be on my side." To resist the fate of the engagement, the two begin acting as a "fake couple" that no one must know about.
