Part-Time Couple

Da-in never imagined she would cross paths with Seojun, her first love, under such extraordinary circumstances. When he suddenly reappears in her life, it is not for a simple reunion. Instead, Seojun presents a startling claim: marriage is the only way to escape an impending, fated death. To survive, he proposes a strictly bound, one-hundred-day contract marriage. Caught off guard but unwilling to enter this arrangement on unequal footing, Da-in refuses to be a passive participant. She carefully negotiates her own terms before stepping into an unconventional newlywed life built entirely on conditions and calculations. What begins as a pragmatic agreement soon proves difficult to contain within its rigid boundaries. As the days pass, the artificial nature of their union starts to blur, awakening unresolved emotions that neither Da-in nor Seojun ever truly left behind. The comfortable distance they established through their contract steadily unravels, replaced by a deepening connection that defies their original intentions. With every passing day, the looming deadline draws closer, threatening to dismantle the walls they built and force a reckoning that could change everything between them forever.
