the only reason why we are saying this is bc she actually liked some tweets calling out YG and she also mentioned she wasn't allowed to release all her music, it's not really an assumption.
but maybe she is better person and doesn't hold grudges like you said maybe it wasn't all that bad.
Like that person said . 2ne1 beginning is kinda bang . And YG is more involved back in the day.
And mentor is usually for someone who teach them or guide them to this point . She might not need a mentor anymore now .
But we don't know what happens during her trainee days and early 2ne1 days . He might really help him back then .
