Three intertwined stories illuminate the fragility of trust as weddings approach and couples confront the pull of past choices, present insecurities, and the fear of losing what they already have.
Tae-kyu [Kim Kang-woo] is a former professional baseball player who now coaches for a minor league team. His girlfriend Joo-young runs a successful urology clinic, a detail that secretly underscores the way life has become orderly and practical for both of them. They’ve broken up once before, found their way back to each other, and are now on the cusp of tying the knot. But a week before the wedding, Tae-kyu learns something about Joo-young that makes him feel betrayed and jealous, and what begins as a troubling hunch quickly grows into an all-consuming need to uncover every fragment of her dating history. As his anxiety intensifies, he becomes fixated on the past, searching for clues in conversations, memories, and long-ago promises, all while the clock ticks toward a day that promises happiness but feels increasingly precarious.
Won-chul [Ok Taec-yeon] and So-mi [Lee Yeon-hee] have been a couple for seven years, and their wedding day is fast approaching. Yet So-mi senses a growing distance, a sense that Won-chul may have settled into a comfortable routine rather than stoking real passion. Their relationship is defined by a shared life that feels stable but slightly hollow, and So-mi’s unease pushes her toward a pivotal moment. Several days before they exchange vows, So-mi travels to Jeju Island for a nail art competition, hoping to reconnect with her own ambition and perhaps rekindle the spark she fears fading. There, she meets Kyung-soo, a tour guide and webcomic writer, whose easy charm and creative charisma awaken new feelings within her. The encounter sets in motion a delicate negotiation between long-standing affection and a fresh pull toward something unpredictable and liberating.
Geon-ho, a gentle flower shop owner, is a warm, life-wocused bachelor who believes he’s ready to marry Vika, a woman from Uzbekistan who is younger and strikingly radiant. The couple’s impending wedding is shadowed by a sudden erectile dysfunction that Geon-ho does not see as a failure but as a signal that something else is at play. He seeks help from Joo-young, who reassures him that there is nothing physically wrong, and that stress and emotional pressure can manifest as impotence. As Geon-ho confronts his own insecurities—especially the nagging worry that Vika might be drawn to him for citizenship or status rather than true partnership—he wrestles with questions about what love requires and what it can withstand when doubt arrives unannounced.
Dae-bok [Lee Hee-jun] works at Joo-young’s urology clinic and has recently begun dating Yi-ra [Go Joon-hee], a practical and ambitious wedding planner. Their relationship starts with the energy of new love but soon meets the friction of real-life expectations. Then comes a startling moment: during a baseball game, Yi-ra reveals that she is pregnant, and Dae-bok responds with immediate commitment, proposing right away. Yet as they prepare for a future that should feel certain, their days are filled with arguments and disagreements that hint at deeper uncertainties. Dae-bok’s earnest attempts to reassure Yi-ra clash with her cynical pragmatism about whether their partnership can endure long-term, and the couple is left to decide whether love alone can secure a shared life or if something more substantial must sustain them through inevitable storms.
Across these stories, the drama unfolds not through grand gestures but through quiet moments of doubt and the slow erosion of certainty. Each pair stands at a crossroads where honesty, vulnerability, and the fear of betrayal collide, forcing them to ask what they owe to themselves and to one another when the future they envisioned suddenly feels unsettled. The film uses intimate, everyday settings—the clinics, the islands, the wedding planning rooms, and even a baseball game—to explore how people navigate love’s complexities, the scars of the past, and the fragile hope that commitment might still endure when tested by suspicion, longing, and the uncertainties of life.
