A short chapter, I guess? :3

Just like what Moon Eun Ju said, 3 more trainees transferred to Class A the next day.
Luckily, the 3 new trainees were friendlier than the other 8 that transferred the previous day.
"Park Selena, your hand needs to be raised higher to match everyone else's position," the dance instructor walked over to the blonde and slightly raised her arm. Selena nodded understandingly and looked at Son Kaerol, who responded with a shrug.
"Ki Seul," Kaerol whispered, "Yah Lee Ki Seul!"
The girl with long orange hair turned her head to look at Kaerol, "Hmm..?"
"The dance instructor is coming! Get your off that bench and start dancing!" Kaerol harshly whispered.

It was finally break time, and the 42 trainees plopped down on the ground, exhausted from the intense routine.
"We never had to train this hard in Class B!" Ki Seul complained.
"Well, there's a big difference between Class B and Class A. You'd better get used to the work," Jung Eun Hye said before chugging down a bottle of water.
 "Do you guys do this everyday..?" Selena looked up at the experienced trainees.
"Mhmmm. Everyday, since the first day we transferred here," Go Ah Ra chuckled.
"You guys have gotten used to it, right?" Kaerol tilted her head and asked.
Park Cho Hee nodded, "All of us have been here for 2+ years."
"But being here for so long, we've all become.. sisters. We know everything about eachother," Jung Bo Ra quietly said.
"Hopefully, we'll blend in," Lee Min Young smiled at her sunbaes.
"Don't worry. You'll all eventually blend with us, even those 5 pokerfaces right there," Choi Joo Young smirked and pointed at the emotionless faces of the 5 new trainees that came yesterday.
The five just looked back at the girl with straight faces on.
