In 1950s war-torn Korea, a single day in the town of Sariwon binds four children in a web of betrayal, loss, and chaos. When war strikes, Joon-Hee, Dong-Young, Kang-Hee, and Jang Bin are torn apart, their identities scattered and forgotten. Years later, fate reunites them. Dong-Young, now a high-ranking official, meets Joon-Hee, who suffers from amnesia and lives under a new nam, Duh-Mi. Neither remembers the past they once shared, but something unspoken lingers between them. As Duh-Mi pursues her dream of becoming a fashion designer, she finds an unlikely ally in Jang Bin, now a petty criminal with a hidden past. Kang-Hee, raised under Joon-Hee’s stolen identity, becomes her fiercest rival, both in fashion and in love. Amid rising ambition and buried truths, their lives begin to intertwine once more, stitched together by memory, longing, and a fate they can no longer escape.
