Jo Kwon tweeted this super cute photo of little Jo Kwon and Sunye from years ago when they first began at JYP Entertainment. He wrote: "I found the sticker photos I took to celebrate my two year anniversary of entering JYP. It's with Sunye and Sohee and Yeerang and Sangji during our training period." They must have been around 12-13 years old when this sticker photo was taken! Pretty undeniably cute, right? Do you still spend time with your besties from when you were 13?
