Tell me a kpop gg you've never given a chance and I'll give you recommendations.

Well... there's not much to explain lol. I see that people don't give certain groups a chance very often, and even though I myself don't like a couple of ggs, I can appreciate a songs that I like by them or the artistry or the vocals, etc.
P.S: You can give me an example of the kind of kpop gg you like so I can cater to you better.
