She's headstrong and hard-headed person.She's bubbly,sassy and very stubborn,she doens't like people to nag at her.Wei is very honest,if there is something she hates,is being lied to,she is also very outspoken,she's not afraid of speak her mind,even if it brings her trouble,Wei will face the consequences,no matter what they are.But,hey,looks are decieving aren't they? Well,on the outside she may seem completely innocent and harmless.Wrong,she can be the devil's son when she wants to and trust me,you don't want to face her bad side.

Aside from from those chaos above, she's actually a sincere person and she really cares for her close friends and families.She's really trustable,so if you ever have a problem,she will put aside her childish antiques and do whatever it's in her power to help you. If her friend is insulted in front of herself with or without the presence of her friend, she'll defend her friend. She's mischievous and rebelious, her mind is used for thinking new foolproof pranks,she's a good listener,despite being so childish,she pays attention and turns serious when it's needed. Wei is also an  optimistic person, she'd find any positive side on someone or an occurence.

Wei was born in  QuingDao ,China,she lived there until she turned ten and her family moved to South Korea because of bussiness matters(her family owns a make-up franchise).Once she arrived to Korea,she learned the language,she also learned to speak English since her parents thought it was going to come in handy if they were going to travel again.Wei eventually started to get use to her new environment.As Wei is only child,she has no siblings,she often got bored,specially since her parents were always out,traveling,so she wandered over  Seoul's streets just to distract herself and one she stumbled upon underground clubs,were people hang out,eventually Wei got attached underground hip-hop style.She started to rap and sing,she didn't care if she sounded bad,she loved to do it.So when she turned 14 she decided she wanted  to be a kpop star,like GDragon or Teddy.Wei attended to many auditions,much to her parents displeasure who wanted her to take over the franchise.Finally Wei was accepted YG Ent. when a man saw her performing in the streets her rapping skills and at the age of 15 she became a trainee in YG Ent. and now she is prompt to debut in Just 4 U Mandarine sub-unit.

 He's a troll. really ,he loves pranks and jokes and can be annoying sometimes.A joyful and carefree person.He's very passionate in his singing and often tries to improove it,even though having to sing in a different language that's not his native language.He's someone reliable and honest,sometimes too much.

H's also a caring person. He would do anything to protect her and if her pranks her,he is careful not make her cry or hurt her badly,just silly things,nothing serious.
 

They met through Tao,as Wei practices Wushu,she goes to the same gym as Tao and one day Jongdae came to the gym with Tao,there Jongdae saw Tao talking to Wei and since then Jongdae went with Tao to the gym(although he did no exercise) just to annoy Wei,later they became freinds.

Jongdae loves to prank her and to bicker with her.Often he will try to hug her and to squeeze her cheeks and Wei will glare at him and threaten him to hit him with her Wushu stick.Appart from those fun,silly moments,they have their romatic moments ,when Wei is sad,he will comfort her and hold her.Even though her teases her and annoys her,he would protect Wei if he sees someone bothering her or being mean to her.They're really close,Jongdae knows almost everything about Wei,what annoys her,what she hates,what she likes,what makes her sad...and Wei(even if she hates to admit it) knows also everything about him and even though she claims that he is annoying,she is glad and likes the attention Jongdae gives her.
