Liriell, a mysterious girl who lives in the human world as a flower arranger at the Flower Gallery store, holds a profound secret about her origins. Beneath her warm and cheerful demeanor, she is actually a white elf banished from her people and has lived for hundreds of years. Her serenity begins to crumble when Velmor, a cunning, half-mad dark elf who has long haunted her, reappears in search of the Black Diary—an ancient magical artifact that holds the link between Liriell's soul and her people's past. A misunderstanding manipulated by Velmor leads the wizard Isran to hunt Liriell, leading David, Mr. Magic, and Fernando to become embroiled in a magical conflict that slowly escalates into a battle between light and darkness.

More than a century after losing her first love, Liriell lives a quiet life as a florist. Fate reunites her with the reincarnation of Willem, the man she once loved in a past life, who now lives as Malio. However, Malio is already engaged to Tamara. Caught between cherished memories, lingering regrets, and the relentless passage of time, Liriell must choose between holding on to the past or letting it go for someone else's happiness. A heartfelt story about a love that arrived too late.
