Fated to Love You

Kim Mi-young, a timid and overly accommodating office worker nicknamed 'Post-it Girl,' boards a cruise ship hoping to strengthen her relationship with her boyfriend. Chaebol heir Lee Gun, CEO of Janetal Corporation, is also on the cruise planning to propose to his girlfriend Se-ra, a prima ballerina. Through a series of misunderstandings and mix-ups involving room assignments and medication, the two strangers end up spending the night together.

Mi-young and Gun wake up in shock after realizing what happened between them the previous night, both desperately trying to locate their respective partners on the cruise ship. Gun discovers that Se-ra has left the ship early for an overseas opportunity, while Mi-young's boyfriend Daniel also fails to show up as planned. The two part ways awkwardly, hoping their accidental encounter will remain a forgotten secret.

Mi-young returns to her normal life working at Janetal Corporation, unaware that Gun is her company's CEO, and the two have an embarrassing reunion at the office. Gun's grandmother, the sharp and commanding family matriarch, pressures him about marriage and the future of the Janetal family line. Mi-young begins to suspect something is wrong with her health and visits a doctor, receiving shocking news.

Mi-young is confirmed to be pregnant from her one-night encounter with Gun, sending her into a panic about what to do next. Gun is informed of the pregnancy and, pressured by his grandmother who is overjoyed at the prospect of an heir, he proposes a contract marriage to Mi-young. Mi-young, overwhelmed and unsure, struggles to make a decision that will change her entire life.

Mi-young reluctantly agrees to the contract marriage after Gun and his grandmother present her with terms and financial incentives to support her family. The two begin their awkward cohabitation, with Gun setting strict rules and maintaining emotional distance while Mi-young tries to adapt to her new luxurious but uncomfortable circumstances. Se-ra returns from abroad and Gun struggles with his lingering feelings for her while fulfilling his obligations to Mi-young.

Gun and Mi-young's contract marriage becomes public knowledge, shocking both their social circles and creating tension with Se-ra, who had not expected Gun to move on so quickly. Mi-young faces hostility and judgment from those around her who assume she trapped Gun with the pregnancy, but Gun unexpectedly defends her in a public moment. The two begin to develop small, tentative moments of genuine connection amid the awkwardness of their arrangement.

Gun begins to notice Mi-young's quiet sincerity and selflessness, finding himself more charmed by her than he anticipated. Se-ra confronts Gun about their relationship, making clear she still has feelings for him and complicating his emotional state. Mi-young, sensing that Gun still loves Se-ra, tries to suppress her own growing feelings to avoid getting hurt in their temporary arrangement.

Gun takes Mi-young on a work trip to Macau, where the two spend more meaningful time together and Gun becomes increasingly protective and attentive toward her. A romantic moment between them hints that Gun's feelings are beginning to shift from obligation to genuine affection. However, Se-ra reappears in his life, and Gun is torn between his past love and his growing bond with his contract wife.

Gun openly begins to choose Mi-young over Se-ra in small but significant ways, confusing both women and himself about the nature of his true feelings. Mi-young's health becomes a concern as her pregnancy progresses, and Gun grows more attentive and worried about her well-being. The two share a closer, warmer dynamic, and their relationship starts feeling less like a contract and more like a real marriage.

Tragedy strikes when Mi-young suffers a miscarriage, devastating both her and Gun, who realizes how much he had come to care about their unborn child and about Mi-young herself. The loss forces the two to confront the terms of their contract marriage, which was originally based solely on the pregnancy. Gun, now aware of his genuine feelings for Mi-young, struggles with whether to let her go or fight to keep her by his side.

In the aftermath of the miscarriage, Gun and Mi-young face the painful question of whether their contract marriage should be dissolved as originally agreed. Gun makes the difficult decision to let Mi-young go, believing he is acting in her best interest despite his growing love for her. Mi-young, heartbroken but composed, begins preparing to leave the life she had started to build with Gun.

Mi-young leaves Gun and travels abroad to start a new life, throwing herself into studying art and pottery in a new city. Gun, consumed by regret and the realization of how deeply he loves her, falls into a period of depression and self-recrimination. Se-ra, witnessing Gun's devastation over losing Mi-young, begins to understand that his heart truly belongs to someone else.

A three-year time jump reveals that Mi-young has blossomed into a confident and talented woman who has built a new life for herself abroad as a ceramic artist. Gun has also changed, throwing himself into work while quietly carrying his heartbreak, and has not moved on romantically. The two are brought back into each other's orbit when circumstances conspire to reunite them in the same city.

Gun and Mi-young have a tense and emotionally charged reunion, with Mi-young having rebuilt her confidence and no longer the pushover she once was. Daniel, who has been a supportive figure in Mi-young's new life abroad, makes his romantic interest in her known, creating a rival dynamic with Gun. Gun is simultaneously struck by Mi-young's transformation and desperate to reconnect with her, but she keeps him at a careful distance.

Gun pursues Mi-young earnestly, trying to apologize for the past and win back her heart, but Mi-young is guarded and unwilling to be hurt again. Daniel actively courts Mi-young and challenges Gun for her affection, leading to tense confrontations between the two men. Mi-young begins to waver as Gun's sincerity becomes increasingly hard to deny, but old wounds make it difficult for her to trust him again.

Gun makes bold and heartfelt gestures to prove his love to Mi-young, refusing to give up despite her resistance and Daniel's competition. Mi-young begins to soften as she sees how much Gun has genuinely changed and how deeply he regrets letting her go. The emotional walls between them start to crumble, and the two share a vulnerable and honest conversation about their shared past and lingering feelings.

Mi-young finally acknowledges her unresolved feelings for Gun and the two tentatively begin to rebuild their relationship on more honest and equal footing. However, a health crisis involving Gun emerges, revealing that he has been concealing a serious medical condition that adds urgency and heartbreak to their rekindled romance. Mi-young must grapple with the fear of losing Gun just as she has allowed herself to love him again.

Gun's medical condition worsens, and he pushes Mi-young away once more in a misguided attempt to protect her from pain, causing deep hurt and frustration. Mi-young, now stronger and more resolute than ever, refuses to be pushed aside and fights for their relationship with the determination she never had before. Their loved ones rally around them, and the couple faces the health crisis together rather than apart.

Gun undergoes treatment for his condition and Mi-young stands by him steadfastly, their bond deepening through adversity and mutual vulnerability. The various supporting characters begin to find resolution in their own storylines, including Se-ra making peace with the reality of Gun and Mi-young's love. With the crisis beginning to resolve, Gun and Mi-young look toward a future together with renewed commitment and honesty.

Gun recovers and the couple reaffirms their love in a genuine and joyful reconciliation, getting married again on their own terms out of true love rather than contract or obligation. Mi-young's transformation from the meek 'Post-it Girl' to a self-assured woman who knows her worth is celebrated by everyone around her. The drama closes with Gun and Mi-young embracing a happy future together, their fated love story finally arriving at the joyful ending they both deserve.
