Despite aespa’s Savage taking the win against ITZY’s LOCO, Ryujin stayed back to celebrate with them for some time on stage, which won fans' hearts. The 2021 MAMA interaction going viral shows that fans love their group interactions as well.The fourth-generation collaboration at 2021 MAMA included solo opening performances from Yeji, Karina, ATEEZ’s Wooyoung, TXT’s Yeonjun, Stray Kids’ Hyunjin, and ENHYPEN’s Heeseung.
