The eldest of his daughters, Yuhwa, was confronted by Hae Mo-su while she was bathing in a river, and eventually she married him without her father's permission.
However, after the official marriage ceremony was held, Yuhwa escaped Hae Mo-su's chariot before they could ascend to heaven and she returned to her father.
Because his daughter's actions brought disgrace to him, Habaek had his lips stretched out and he exiled her to a stream in Dongbuyeo, condemning her to a mortal life.
The story of Habaek also lacks mentions of Hebo's accomplishments (and vice versa) which are integral to his identity such as the Heavenly Questions, only discussing individuals who are important to the history of Korea.
This aligns with Lady Yuhwa's pregnancy story where she bore Chumo after the sunlight touched her uterus being the daughter of a sun god.
