Aired on January 2, TV Chosun's 'Idol Party' welcomed the MAMAMOO members to the stage.  

On this day, when Hwa Sa, known for her sexy image, was asked by the MC if she was sexy during her younger days, the singer gave a confident answer.  However, Whee In stated otherwise, "She wasn't sexy when she was younger," making the audience laugh. The two have been good friends ever since junior high.

Whee In then went on to talk about an incident from their school days, saying, Hwa Sa refused to let her have a bite of her corn dog.  Whee In expressed her sorrow, "She seriously ate the whole thing all by herself."  Hwa Sa switched to defense, saying, "Corn dog was expensive. She could've just bought one herself but kept on insisting for a bite."

On the other hand, MC Leeteuk chose Hwa Sa as the 'member with the least appealing facial features,'  "The reason is her swollen face from pulling out her wisdom teeth."
