• Hates people who think to highly of themselves. ("like Myungsoo"- JiAe says jokingly.) the reason for this is because of an incident with a certain 4D Prince.During their first meeting Myungsoo commented that JiAe should fix her attitude , saying "kids  should be more respectful  to others especially towards their seniors " and JiAe replied "You should say that to your self" and that is how their Cat and Dog relationship began. Though recently their relationship is improving. Still JiAe claims that she dislikes him the most  >:P

• Flirts and playboys. She says that they are just pain DISCUSTING and a sore to the eyes.

• SKINSHIP and Fan service !  : I hate it the most in the world , especially with UGLY Sungyeol (Sungyeol is one of her closes guy friends). I just don't get why people like skin ship so much! its so annoying -_-.

• Gossip and Rumors :  I have heard a rumor lately, Its about me liking a certain someone ( myungsoo) .... I don't know where that came from (sungyeol started it!) . I think its stupid!  I just don't get it ! 

JiAe's parents divorced when she was only 9 years old, because of this she grew up separated from her mother. She lived in the US with her father , Since her parents divorced JiAe learned to be mature and independent despite her young age , this i because she does not want to worry her parents instead she wanted to be the one to take care of them and give joy  and inspiration through her singing.

Since her parents divource , JiAe's father has been busying himself with work in the company and because of this JiAe grew up not seeing her father often.  Growing up JiAe became cold and distant with her father for a period of time , but as time went by JiAe realized that her father was probably trying to forget her mom (whom have cheated on him with a younger man) by busying himself with work. With this in mind JiAe began to understand her fathers actions and instead of being cold and distant towards his father , JiAe tried her best to be more acquainted with him. She wrote letters to him when he is a way and sings for him he is at home. Her father is now her inspiration as she reach for her goals of becoming a singer. She wishes to be able to bring joy to her lonely father through her singing and dancing.

JiAe haven't seen or heard any news about her mom since the divorce, it is unknown if she is still love or not and how she is doing. All she knew is that her mother had  left JiAe and her father for another man, because of this she  grew to hate her mother for abandoning them (JiAe and her dad) for another man. Despite her hate JiAe still longs for the love and care of her mother, she wishes that someday she would be able to see her mother again and be able to talk to her on why she left.

Lee Sungyeol | 22 | Idol/ member of INFINITE | cheerful choding | 

We first met during our trainee days.  I really don't know how I became friends with an annoying idiot like him. Sungyeol is the type of person who is a cheerful choding , he express himself really well through his actions and he is very comfortable with skin ship. I on the other hand is a person who can be cold and indifferent  , I find it hard to express myself through words and actions and is oftentimes misunderstood. Most of all I hate skin ship , I don't really get why people love doing it, ITS DISGUSTING!!!(especially when its with Ugly Sungyeol). He is so annoying! He keeps on nagging me to call him "oppa". tch! Annoying!

Their difference in personality made them closer to one another. JiAe would often by calling him names and even uses informal language with him even though he is a senior. " Sung- who? I don't know a person named Sungyeol." She says this with a straight face. JiAe is known as a person who can be cold, rude and indifferent that is why she has only a few friends so she treasures those that she has like -the "annoying idiot"- Sungyeol.

From the beginning JiAe and Myungsoo's relationship had a bad start , at that time Felicity was  being introduced to Infinite. JiAe was talking to Sungyeol using an informal language and tone calling him an "annoying idiot". Myungsoo heard this and got annoyed with her "rude" attitude. The others already knew that this is JiAe's way of friendhip and it is how she had always been with Sungyeol . Myungsoo did not know this and confronted her saying " Yah! you should treat your seniors with respect! Fix your attitude!" . (with a mocking tone)  " Don't -in to other peoples business, 'Myungsoo-sii '. You don't even know me well to tell me what to do and not to" she said , her annoyance got the better of her. Since then they have constantly quarrel even with the littlest things.Others (especialy SUNGYEOL) often Tease Myungsoo and JiAe because of their fights that are like "an old couple quarreling" (Sungyeol  was the fist who started to call them as "MyungJi Cauple" ). 

JiAe is known for her straight forward and quick tempered personality,that is said to rival Myungsoo's. Their great similarity in their personality they tend to clash with one another and have misunderstandings, until one day it all changed it was the day that JiAe began to notice him not as a Rival but as a person she likes. (she tries to hide this by being cold and indifferent)

She realized she likes Myungsoo:

*It was after one of the groups intense trainings, everyone was having a brake. JiAe was sitting on the bench drinking water , then Myungso who was holding a box of Pokki sat beside her. They were both quiet , until Myungso broke the silence. "Here , I don't want it anymore" said Myungsoo as he gives JiAe the box of Pokki.  JiAe was going to decline but Myungsoo had already left and placed the Box on her hand. JiAe stared at his retreating back , then grabbed the box and opened it with a small smile on her face.
