First, IU didn't say she sent offers to Rosé, she said she is interested to work with her.
For Jennie, Yg love money. Variety shows in Korea didn't pay that much. So, it is more for exposure especially for new groups. Yg didn't see the benefits to send her in variety shows in Korea.
Guess how many Lisa made during Youth with you 2, it was 5.7 million usd and more than 11 million for two season. See, she is their cash cow.
I definitely say that each of the members get mistreated by YG, by you cannot deny that Lisa as the foreigners are receiving the worst. She does a lot of jobs but her payment will not match it, do you understand?
