Kwun Hyuk Soo has taken to his personal Instagram to bid final farewells to late idol Moonbin of ASTRO.

On April 22 KST, the television personality shared two messages tagging Moonbin's Instagram account. In one, he shares a selfie and writes "Rest in peace," while in the other, he shares a photo of the sky, writing in Korean, "Goodbye, Bin."

Previously, shortly after the news of Moonbin's passing was confirmed, Kwun Hyuk Soo expressed his initial reactions in two different Instagram posts, writing, "RIP" and also "I love you. I'm really so sorry and grateful for you and miss you. Don't be in pain, and be well."

Meanwhile, Kwun Hyuk Soo and Moonbin first became friends after appearing as co-stars on XtvN's variety program 'The Ultimate Watchlist of Latest Trend,' which they appeared in together in 2018 and 2019.
