April 19 marked two years since the world lost ASTRO’s Moonbin, and his sister Moon Sua, from the girl group Billie, honored him in the most touching way possible—with a letter straight written from the heart and a tribute song. Starting with “Oppa, are you doing well?” her words were proof of sibling love and grief.

Moon Sua shared the ups and downs of life without her brother: the laughter she fakes, the strength she fights for, and the dream encounters that keep her going. Her biggest comfort? Believing Moonbin would be proud of how far she’s come. She also performed a cover of “Always Remember Us This Way,” originally sung by Lady Gaga, with Moonbin in mind.

She ended her message with an emotional promise: “If there’s a next life, I’d still want to be your little sister.” The tribute, part of the “Memory of the Moon” project featuring 22 artists, includes big names like ASTRO’s MJ, JinJin, Cha Eun Woo, and Yoon Sanha with members from groups like Monsta X, Seventeen, Stray Kids, SF9, Viviz, and more, all uniting to pay homage to the late K-pop star.
