Seoul: A Door to the Future

When Lin Xiuyuan opens a mysterious door in 2013 and steps into the year 2025, a series of profound encounters unfolds across time. The past version of Jung Soo-yeon meets her future self, Jessica, to reconcile their divergent paths. They stand together before the graves of Sulli and Goo Hara, mourning friends lost too soon. Meanwhile, Im Yoon-ah, having spent decades trapped in mediocre films, receives guidance from her accomplished future self and sets her sights on winning the Blue Dragon Film Award. Ham Eun-jung, whose career was derailed by a tragic accident, confronts him directly, demanding to know why he did not open the door two years earlier. Beside her stands Park Ji-yeon, who has just reached adulthood yet must witness the painful reality of her own divorce. Through this temporal gateway, destinies are revisited, regrets are voiced, and second chances emerge against the backdrop of K-pop and Korean cinema.
