On the June 24 installment of Jessica and Krystal's reality program, the two girls had a get together with their friends for a nice chat in the park.  During this portion, Jessica's friends recalled how shy Krystal used to be in the past, cutely teasing her for being a crybaby.

One of Jessica's friends said, "I remember you.  You were always crying in the bathroom," while another added that Krystal was always hiding behind Jessica.  

At this point, Krystal was called a crybaby in the past, but Jessica explained that neither girls ever cried because they were sad but rather because they were frustrated.  Jessica also revealed that she used to be very shy, as well.  When she first had to do camera testing, she could not look into the camera and cried.  Krystal empathized, saying that she hid in the bathroom. 

Also when they were with their friends, Jessica found out one person was dating a younger man.  She said she did not like being called "ya" (informal way of addressing somebody) by a younger guy, so she would want to be called Soo Yeon-ah (her Korean name). The others said that was the same thing, but she repeated that she really didn't like being called "ya."  When asked if she would date a younger man, she said she wouldn't be able to.
