Hyomin has a weak spot when it comes to looking out for members who were younger than her.

There was Jiyeon, her baby dino~

Then came along Hwayoung and Ahreum. 

For two separate occasions, Hyomin got really close with the new members. Hyomin just wanted to look out for them, she was just being her usual caring self but Jiyeon didn't like it.  The younger girl didn't like the idea of her Hyomin unnie getting too close with the new members. She wanted Hyomin for herself, and hence she started ignoring her unnie and tried to make the older girl jealous and get her attention by hooking up with Eunjung. But little did she know that the older girl was quietly hurting because of her childish action. And never will she expect things to take a turn for the worse.

"'No. 9' is the name of the strongest type of painkiller avaliable in the U.S"  

Hyomin's eyes lit up when she heared the word "Painkiller", she knew that this is one way to numb the pain inside temporarily.
