About Eunwoo & Moonbin

Cha Eun-woo (Eunwoo) and Moon Bin (Moonbin) were both members of ASTRO, the six-member boy group that debuted under Fantagio Entertainment in 2016. Within ASTRO, they were frequently recognised as two of the group's closest members — sharing easy warmth and comfort with each other that fans saw across years of content. Eunwoo went on to become one of the most prominent ASTRO members in the public eye, building a substantial acting career alongside his idol work. Moonbin was a main dancer whose precise stage energy and gentle offstage personality made him deeply beloved in the ASTRO fandom (AROHA). Their closeness within the group was well-documented across ASTRO's variety and reality content. Moonbin passed away on April 19, 2023, at the age of 25. His loss was felt deeply across the K-pop community and most keenly by his ASTRO members. Cha Eunwoo has spoken publicly about the grief he carried afterward, and in January 2025 paid heartfelt tribute to Moonbin at a commemoration around what would have been his birthday, performing 'For a Long Time Afterwards' with tears in his eyes and quietly saying 'Happy Moonbin Day.' In April 2025, ASTRO members co-wrote and released the tribute song 'Memory of the Moon' alongside a wide circle of fellow idols who had loved him. This pairing is remembered with the warmth and sadness appropriate to a genuine friendship cut short.

The Eunwoo and Moonbin pairing holds a uniquely tender place in ASTRO's fandom. AROHA celebrates the warmth of their documented friendship while holding the grief of Moonbin's loss. Fan content for this pairing is often reflective and memorial in character — a community choosing to honour what was real between two people who shared years of their lives as members of the same group.
