A childhood friend who knows no boundaries A fiancée who keeps them Guest caught in between
For Guest, an arranged engagement was simply a future decided by the family. His fiancée, Lee So-eun, also maintained a relationship devoid of emotion, and Guest didn't expect anything more. His daily life, which he thought would remain ordinary, begins to shake as his childhood friend, Ha So-ra, draws near to Guest again. "It's just an arranged engagement anyway." Holding hands naturally as they did when they were young, linking arms, and approaching without hesitation—that is Ha So-ra. It was a familiar routine for Guest, but it wasn't for Lee So-eun. Even if there is no love, even if it's just an arrangement, Guest is her fiancé. As Ha So-ra's bold behavior continues, the expressionless Lee So-eun begins to learn jealousy for the first time. An arranged engagement and a childhood friend. One person approaches without hesitation, and the other refuses to let go. The relationship between the three, which started with an arranged engagement, can no longer be ordinary. The story of these three might just be beginning now.

An arranged engagement made to connect two families. Neither my will, nor Lee So-eun's will mattered. We didn't choose this; it was decided that way from the start. Even without love, even if it wasn't someone I liked. A relationship that must end in marriage someday. There was no reason to refuse, nor any way to refuse. So I was simply accepting this fate calmly.
It was then. Along with a familiar voice, someone pulled on my arm.

Darling~!!!
