The girls came home after they got school earlier

*At the Southside*

"I can't believe it..." Yena said.   "Yeah.... me to..." Yujin agreed.   All the girls are silent because of what's happening.   They can't believe they're going BACK to the Northside.    The Southside and the Northside girls used to be really close... They are a group back then but something happened that made their friendship miserable.

*FLASHBACK*

The girls are heading to school...  "Yah! guys I have some good news!" Jeongyeon said shouting.  "What is it Jeongie?!" Nayeon asked Jeongyeon.  "I have a girlfriend now!" Jeongyeon said.   When Nayeon heard what Jeongyeon said her smile faded.  Nayeon is in love with Jeongyeon since they met.  "Wow bro!" Yujin said.  "Congrats!"

Yujin curiously asked.    "Maybe tomorrow" Jeongyeon replied.  "Oh yeah" Yujin said.   "Oh by the way what's her name?" Yujin asked.   "You'll find out tomorrow" Jeongyeon said.   "She attends the same school with us" Jeongyeon added.   "Oh cool then I can't wait bro!" Yujin said excitedly.
