Yerin surprisingly is a good singer. I thought that she was the third best during Glass Bead era, then dropped to fifth when she sang in Hidden Weapon, but now, damn, she held that powerful voice all along. Umji and SinB sound great as well, and don't think I missed that adorable maknae line twirl moment. And Umji's narration in the start and her harmony with Sowon ♡ Speaking of Sowon, wow, she can actually sing. I always thought low of her vocal capacities but I take it back, I guess GB and MGT are just too high for her kind of specialty. (But I wanted her to rap badly ;n;)
