lainaotabi was the youngest queen of king thongaren () of the underworld kingdom (). queen laikhurembi was the first wife of the king. poireiton, thongalel's younger brother, was about to leave on a journey to "tai pang pan". the king asked laikhurembi to go with poireiton as his wife because poireiton's own wife had died. however, laikhurembi did not want to go. trees had already been planted to honor her as the king's wife. so, instead of laikhurembi, lainaotabi was sent to accompany her brother in law poireiton as a wife.
