His older brother, Buyeo Abang, became the 17th kin, Asin of Baekje. The second brother, Hunhae was sent to Japan as a political hostage but returned to Baekje during his brother's reign. His brother, King Asin, died in 405 and Hunhae served as regent for Asin's son (who was also in Japan as a political hostage) who was returning from Japan. Seolye, who wanted to become the next king had his brother Hunhae killed but was himself killed by the returning Jeonji and the prime minister.[1]
