Seolhyun,Hyuna and Suzy are among the biggest example
Another example :
Gugugan‘s Mina and Sejeong have been sharing their personal profits with the rest of GUGUDAN members ever since they debuted in I.O.I. (what even ???)
i will never understand why tho ... its due to the contract but isnt unfair ? imagine working hard 24/7 without any rest only for ur income to be divide with others who actually didnt do anything and just chilling on dorm ? Its not group work its an individual work
