Wiwin gave birth to a child as a result of her relationship with a mermaid named Tiara. Tiara's birth brought about a major disaster until a tsunami occurred in the area where she lived. When the tsunami waves hit and the residents ran to safety, Tiara was swept into the sea and was saved by a dugong named Irena. Several years later, Tiara, who was raised by Irena, was caught by a group of fishermen and locked up. On the one hand, Vano, who happened to be visiting his grandmother's residence, heard Tiara's voice asking for help. Vano felt sorry and helped release Tiara and even taught Tiara to adapt to human habits.
