Once, there was a raja named Sibu who had a beautiful daughter named Hiyas. It was said that she fell inlove with the rival prince named Bunyi.
When the raja found about their secret affair, he commanded his men to kill Bunyi in the battlefield. Bunyi's death caused a great deal of heartache to Hiyas that she sworn from the fields that she and Bunyi first met that evryone in the baranggay will feel her pain. She cried to her death.
Years after, a plant emerged from the said fields and everyone who passes by and came near to that plant can't stop crying for no reason at all.
Thus, they named this plant Sibuyas.
