To Chaeyoung Jennie has always secretly been her favourite co member in Black pink. She looks up to Jennie on and off stage. Yes Jennie can be cold and have an attitude at times but thats just Jennie being Jennie. 

Chaeyoung still remembers the day she arrived at YG. She was just a kid from Australia who left everything behind to chase a dream that seemed unattainable. She was terrified as any 14 year old would be, but then she met Jennie. Jennie took Chaeyoung under her wing and taught her how to survive and thrive in the competitive environment of being a trainee. Everyone knew Jennie was always going to debut and for good reason. but she made sure Rosie as Jennie liked to call Chaeyoung, was going to debut too. Whether that be staying back for hours after practice to help Rosie perfect her dance routine, or staying in to help study Korean so when she debuted Rosie was perfect. So to Chaeyoung, Jennie is everything.

But the question is, what is Rosie to Jennie?
