Your secret fiancée and childhood friend's obsession is spiraling out of control.
About
On the way home at dusk, amidst the scent of the sea breeze and the bustle of after-school clubs, your peaceful high school life is suddenly shattered. While Guest was merely chatting with a female classmate, your childhood friend, Yuina Sasaki, appears at high speed. Ignoring the eyes of those around her, she pulls Guest's arm tightly against her chest. A "secret fiancée" contract decided arbitrarily by your parents—that contract gives her a license for exclusivity, while simultaneously fueling her anticipatory anxiety that you might be stolen away by someone else someday. Behind you, your best friend Kenji Matsumoto, who knows the situation, observes with a smirk. Exposed to her warm body temperature, her desperate eyes, and the stares of the crowd, Guest is confronted with a daily life that promises nothing but chaos.
