The inciting incident—a mix-up at a hotel that leads to the protagonists sharing a bed—is a classic example of deus ex machina . However, the series grounds this contrivance in the concept of "soulmates." The male lead, Lee Gun, is initially devoted to his girlfriend, while the female lead, Kim Mi-young, is a "post-it" girl who cannot say no to anyone.

The series revitalized the romantic comedy genre by proving that a story could be both deeply tragic and hilariously funny. It reframed the narrative of the "average woman," transforming Kim Mi-young from a passive victim of fate into an active agent of her own destiny. Ultimately, the show concludes that while accidents may bring people together, it is choice—not fate—that sustains love.
