Here is the 4th contestant, Justine Jung

Justine walked inside the new dance room to see Jennifer glaring at some girl.

"Unnie?" Justine called out and then saw Hee Sun. "You're here too?"

"Justine," Jennifer greeted Justine with a smile.

"Hi," Justine said to Hee Sun.

"Are you related to Krystal-ssi and Jessica-ssi?" the other girl asked.

"Yes," Justine rudely said. "I'm their cousin. How are you?"

"My name is Kim Girim," Girim smiled.

"What's your specialty?" Justine asked.

"Um...dance and singing. What about you?"

"Dance and rapping. How old are you?"

"16," Girim answered. "I turned in June."

"So that means I am older than you," Justine smiled. Then she turned to the older girls. "Do you think we will debut together?"

"I hope so," Jennifer said. "I'm getting too old to be a trainee."

"But you are one of the cool trainees. You danced for Super Junior and TVXQ."

Girim beamed at Jennifer. "Really unnie?"

Jennifer blushed," ...yes."
