She get the high note in dice song that makes viral because she is not just pretty. They could just give it to lily but they not. Dash and run for roses, haewon and lily already got ad libs and high notes, putting sullyoon might just make her be overshadowed by lily and haewon just like when they put 3 of them in the viral dice high note performance. If you dont have any idea what the agency try to do without left the others because they just 2 years old group, you better show the example of not wasting one. People like you who always complain like baby not know any process and giving negative energy makes me feel cringe and wanna puke

They don't get challenging parts in their songs?? Oh my God, you must be joking right?
