There's Pak Wayan, a wise old fisherman from Bali who shares tales of the ocean's secrets; Ibu Sri, a kind-hearted market vendor from Yogyakarta who teaches Luna about the significance of blue in Indonesian culture; and Rio, a charming young musician from Jakarta who introduces her to the vibrant rhythms of the city.
