K-pop girl group Billlie’s member Moon Sua, the younger sister of ASTRO’s Moonbin, will be handling all the responsibilities of her brother’s funeral as Chief Mourner, as per several South Korean outlets on April 20, 2023. The duo shared a deep bond that was known by many as they often went viral for their interactions.

The role of Chief Mourner, aka the Sangju, is of great importance in the South Korean funeral tradition. Usually, the responsibility is given to the eldest son or grandson, or the one closest to the deceased. Sangju is in charge of preparing the body, making sure the funeral wake goes according to Korean traditions, and organizing everything from start to finish.

In Korean custom, it is believed that the Sangju "lets" their loved one pass away. In return for this, they are tasked with all pre-burial, funeral rites and memorial responsibilities.

In recent times, pre-funeral rites are usually done by professionals. However, Chief Mourner still has to be a central part of it. Other responsibilities of Sangju include seeing guests and accommodating them.
