Hoi is a curious boy who always felt a little bit different. The tides seem to whisper to him; the rain follows his moods. While other kids laugh and play, Hoi drifts through life like a message in a bottle - yet full of mysterious light waiting to surface…

A clever young witch, named LUMI, discovers what no one else could see: a spark of OCEAN MAGIC sleeping inside Hoi. Together, they set out to understand this gift - magic born not of spells, but of emotion, love, and the living sea itself.
