tbh sometimes i'm astounded that he's a main vocal because while he has the power, he can't sustain a note for very long, doesn't have great pitch, and his voice is so painfully nasal whenever he has to sing high and loud, which in the world of kpop main vocals is always lmao

that said, i looove his voice in the lower ranges. obviously my bias is showing but idk can i just leave this here, it's him singing "one late night in 1994" on sketchbook and he only shrieks once or twice :')
