After Moonbin's death, Sua's birthday is attended to by ASTRO's Sanha.

Moon Sua's birthday was spent in silence following the death of her brother Moonbin.

However, fellow ASTRO member Sanha cheered her up by organizing a birthday celebration for herOn September 9, Sanha posted pictures of Moon Sua smiling broadly and posing in front of a cake with cream smeared on her cheek, with the comment, "199999 Happy Birthday Sua." Many people were moved by Sanha's preparation of seaweed soup, a customary birthday meal.

Supporters reacted strongly, thanking Sanha for replacing Moonbin and being considerate to Moon Sua. Netizens said, "It's touching how Sanha takes care of her like an older brother," and "Wishing both ASTRO and Moon Sua happiness."

This touching incident reminded me of Moonbin and Sanha's unit effort as "Moonbin & Sanha."
