What Is Calla About?
The premise of Calla in 274 words, with nothing given away. The full story follows below.
In a quiet city where mornings arrive with a delicate fragrance, Seon‑woo finds his routine interrupted by an unexpected gift: a pristine bouquet of calla lilies accompanied by a single musical note. The anonymous gesture becomes a quiet obsession, a puzzle that colors his days with both curiosity and longing. Each new delivery deepens the mystery, prompting him to trace the source of the music and wonder who might be watching him from the shadows.
His search leads him onto a crowded bus, where he first notices Ji‑hee, a graceful florist whose shop carries the same lilting melody that threads through the lilies. Captivated by her warmth and the uncanny connection, he allows his imagination to fill the gaps, seeing in her the possible author of his daily marvels. Their brief encounters blossom into a tentative romance, and he soon gathers the courage to ask her out, hoping the promise of a shared moment will finally reveal the hidden admirer.
Three years later, the memory of that fleeting love still haunts Seon‑woo, now on the cusp of his own wedding. A desperate wish to rewrite the past seems to echo back to him, offering a fleeting chance to revisit the day that changed everything. With time looping back like the soft refrain of the lilies’ song, he finds himself standing at the edge of a day that holds both hope and unanswered questions. As the hours slip away, the search for truth becomes as much about confronting his own yearning as it is about uncovering the identity behind the petals, setting the stage for a new journey toward an uncertain, but unmistakably human, destination.

Every morning, Sun-woo Song Seung-heon receives a calla lily with a musical note attached, a mysterious ritual that makes him wonder who his secret admirer might be. One day, on a crowded bus, he encounters Ji-hee Kim Hee-seon, a woman whose warmth seems connected to the recurring gift. He notices the same musical motif echoing from the flower shop where she works and quickly links her to the anonymous sender. Enchanted and hopeful, he asks Ji-hee out, inviting her on a date to a local hotel, and she agrees.
At the hotel, Sun-woo arrives to find Ji-hee taken hostage, and, to his horror, murdered before his eyes. The shock of that moment lingers as a deep, driving grief that reshapes his days and future.
Three years pass. Sun-woo is on the verge of his own wedding, yet the memory of Ji-hee continues to haunt him, guiding his choices with a mix of longing and regret. His desperate wish to revive her magically comes true, and time is turned back to the day of the fateful hotel date, granting him a 24-hour window to turn things around and save her life. As he uses this chance, he discovers a crucial truth: the lilies did not come from Ji-hee herself; they were sent by Su-jin Kim Hyun-joo, Ji-hee’s friend, who carried the mornings’ gifts three years ago. This revelation forever shifts his understanding of the past.
Transported back to the present by the force of this discovery, Sun-woo must begin a new quest for his true love, Su-jin. The story follows his emotional journey as memory collides with reality, and as he weighs desire against duty, longing against the possibility of a different future. It blends romance with a soft, magical time-loop mechanism, driving Sun-woo to confront hard truths, reexamine loyalties, and decide what kind of love he is willing to fight for in a world where every moment matters.
