The film, currently in production in Seoul, promises a realistic and insightful portrayal of a contemporary relationship. It charts the journey of college sweethearts, Su-hyun (played by Kim Min-ha) and Hyun-tae (played by Noh Sang-hyun), as their decade-long romance navigates the alternating currents of profound affection and challenging frustrations. Unlike many narratives that focus solely on the initial sparks of love, "Messily Ever After" aims to explore the intricate emotional landscape that evolves after the "honeymoon phase" concludes, shedding light on the enduring mix of devotion, exasperation, longing, and uncertainty inherent in truly knowing another person.
