The narrative switches between 1979, when campus life and protests shape So-eun's world, and 2000, where Ji-in navigates a present-day university setting. A mysterious HAM radio link connects these eras, letting So-eun and Ji-in converse across decades. This temporal bridge drives revelations about family, fate, and personal choice, guiding the characters toward a shared realization about their destinations. In the end, So-eun moves forward in her own life, recognizing that Dong-hee was not her ultimate destination.

The story unfolds across a university setting and its surrounding city. So-eun and Ji-in interact within classrooms, clubs, and in front of a clock tower, with the HAM radio room acting as a bridge between two times. Key locations include the university campus, the hospital where Sun-mi recovers, and the clock tower that frames pivotal encounters. The city backdrop, including student demonstrations, shapes the characters’ lives and decisions.

🕰️ Time Travel

A central conceit is messages crossing time via HAM radio, connecting So-eun in 1979 with Ji-in in 2000. The bridge creates a fragile yet meaningful bond between two strangers who become confidants across decades. Time acts as both a constraint and a guide for love and identity, forcing characters to reconsider what they believe about fate. The narrative uses this device to explore how people find purpose across eras.

💞 Love Across

Romance is tested by the gap between years, contrasting So-eun's love for Dong-hee with the possibilities the future suggests. The radio link with Ji-in adds complexity, offering alternate paths and echoes of what could have been. The film questions whether love can endure when separated by time, and what it means to pursue a destined relationship. Ultimately, it reframes love as something shaped by choices and revelations about what truly matters.

🧭 Destiny

Characters search for their true destinations within a web of memory, family ties, and sudden discoveries. Ji-in uncovers So-eun's past connections to his parents, prompting a re-evaluation of his own path. So-eun learns that some attachments are not meant to define the future, leading to a graceful acceptance of life as it unfolds. The story presents destiny as something to be understood and embraced, not forcibly altered.

📝 Diary

The radio correspondence functions like a living diary, preserving intimate thoughts across time. So-eun and Ji-in reveal fears, hopes, and family revelations that shape their identities. Their dialogue across years lets them narrate inner lives without meeting in person, creating a parallel narrative thread. By listening across time, they collectively write the arcs of their emotional journeys.
