This is all about the couple Valentuna and Uda-Ah, they have both secret in their lives. After the time that Valentuna found out the true identity of her beloved boyfriend he cursed herself to be his cage (a water cage like bubbles under the lake). To their wonderful town Botolan in Central Luzon. They really love each other that is the reason why it has a tragic/ sad ending. Sometimes we make decisions for ourselves not just to be happy but because the thing is right.
