Jo Jae-mi is Hae-jo's former fiancee, a spirited woman whose own life has reached a crossroads as she faces a marriage she does not truly want. When Hae-jo pulls her into his last journey, she resists at first, but the trip forces both of them to confront the unfinished feelings and old hurts that linger between them.
Over the course of the road trip, Jae-mi becomes far more than a comedic foil. Her warmth, stubbornness, and quiet pain give the story its emotional balance, and her growing willingness to stand by Hae-jo through his illness reveals the depth of a bond that neither of them fully let go of.
Jae-mi's arc is ultimately about choosing what matters to her on her own terms. As she helps Hae-jo seek meaning at the end of his life, she also reclaims agency over her own, making her journey a counterpoint of resilience and tenderness woven through the series.
