Underrated Korean singers? i'm talking under 100k monthly listeners, ideally even less like 10k monthly listeners

Hey guys, I'm a Korean that can't speak Korean! I'm trying to learn now but don't like kdramas or most kpop songs, so who are some underrated or not even rated singers y'all like? Even my western music playlists are filled with songs like "Butterfinger" by HoneyButter (they have like 9k monthly listeners I think?) For Korean music, I like "Please Don't..." by K. Will (I know he's not underrated, I just like that song)
