Insomnia

When the parents of Hee Jin and Young Ho marry one another, the two young people are suddenly thrust into a shared household. Bound together by their parents' union rather than blood, they must navigate the unfamiliar territory of becoming step-siblings. What begins as an unexpected shift in their personal lives forces both Hee Jin and Young Ho to adapt to a new domestic reality, learning how to coexist under the same roof while redefining their sense of family. As they settle into this blended dynamic, the fragile foundation of their newly formed household is put to the test. The transition from strangers to family members brings its own set of quiet tensions and unspoken challenges, leaving both individuals to wonder whether this sudden arrangement can truly endure. Beneath the surface of their everyday interactions lies the lingering uncertainty of whether their parents' marriage—and the delicate bond it has forced upon them—will stand the test of time or quietly unravel.
