She would gone too far wearing herself out by practicing non-stop without noticing the time. She got a bit of sister complex which lead her over protective of her older sister. She got this due to the fact that she almost lost her sister at a accident and she didn't want something bad again. She is not please to see guys surrounding her sister. Don't get on her bad side. She is not someone you could mess with. If anger her, she would take you down with her Taekwondo moves. She dislikes people saying her cute. She is not a fan of doing aegyo in public. She sometimes would acts reckless,without think twice and putting herself in trouble. She never thought the consequences she would face and in the ending hurting the others.

In 2010, seeing her sister got into SM Entertainment to become a trainee there, she wanted to follow too. She tried to enter the SM audition by sending video of her doing song cover of F(x)'s NU ABO but she got rejected. She was scouted by a rep from Simtong Entertainment at her school.The rep told her the company saw her video auditioned for SM audition and asked her tried to join audition for Simtong Entertainment. Ji Hye thought for a while and since she can't get into SM Entertainment and become a trainee with her sister, why not tried out a different one. So she agreed. She entered the audition and to her luck, she passed and got accept into Simtong Entertainment. 

In 2011, she got news from her parents that her sister got into car accident and was hurt badly. What make feel sad was that Ji Hyun had to force to withdraw from SM entertainment for her recovery. Due to this shocking news, Jihyun was unable to concentrate on her training and lept on doing mistakes, earning a few scolding from her instructor. Seeing no improvement on her progress, the CEO even once told her she would kick out if she did  not perform well. Thus, Ji Hye was caught into depression.

Hansol was funny and outgoing, a cheerful mood maker in his group. He also had some aegyo charm hidden inside of him. He got this cute eyes smile that captured every girl's hearts. He is annoying and mischievous, love to tease his fellow band mates. People around him tend to piss off by him easily and wanted to strangle him badly.  It must be hard to imagine a cute guy like Hansol is one of the power dancers in Topp Dogg. He was friendly and polite towards people. He won't hesitate to help people who need help with the choreography. 

When he's on stage, he remove his mischievous side of him and became a charismatic dancer of Topp Dogg. He was serious when came to stage performance and love to be seek attention from his fans. He loves fanservices very much. He would always act bubbly cute in front of cameras and doing skinship with his fellow members from Topp Dogg.

Ji Hye first met Hansol when she was given a day off by the company, she decided to hang out with her older sister. To her dismay, she never thought she would bring a friend along and that person is none other than Hansol from Topp Dogg. Seeing Hansol acting cute and lovely dovey with her sister in front of her, it makes her very mad. She mistakenly thought Hansol has a thing for her sister and wanted to date her (She didn't know her sister has a crush on someone else). Being a over protective sister she is, she would use all means to stop Hansol from getting closer to her sister. 

On other hand, Hansol was oblivious why Ji Hye hate him so much and came in between him and Jihyun. He didn't remember anything he did to upset her. He was starting to get interested with her after they met for a few times. He started sticking around her like a glue whenever they were together and followed her around like a lost puppy. He would also and having some skinship with her. Sometimes he would pout like a sad puppy when Jihye ignored him or bullied him. Jihye was getting sick and tired of Hansol's presence around her, making her going crazy. Her sister would eventually about stealing her best friend away.
