Jongin works at Season's Blooms, a flower shop at the corner of Myeondong, despite knowing next to nothing about flowers. One day, as if by fate, a certain doe-eyed customer visits Season's Blooms to buy flowers for his friend, and unintentionally steals Jongin's heart in the process. Their bond strengthens with the changing seasons, and, although Jongin can't pluck up the courage to confess his feelings to the man, he instead gifts him flowers that speak those words for him. From brief, meaningless encounters, blossoms a pure love like no other.
