Playful and a Goofball
Younghee is a playful girl, the kind of person that'll able to coax your true self out even though you're as awkward as a turtle. She loves to crack jokes and makes a fool of herself like doing weird dances or imitating animal's sound. Oh, and she's a walking pick-up line dictionary, the hilarious edition. Don't be surprised if suddenly she comes up to you and says, "Girl, are you fart? 'Cause you just blew me away." Yeah, she's the girl that'll make you feel embarassed when you two are walking on the mall because she's doing weird dances or making funny noises or laughing just a little to hard.

Emotional
They say girls act according to her feelings, well that quote really fits well with Younghee. She's very emotional, easily angered and easily gets sad. Once something is bugging her mind, she can never forget about it. Younghee will think about it over and over again, wallowing in self pity or wondering why it happened. Once she gets into that state, everything falls apart. Like if somebody bashes her, Younghee will only wallow in self pity and do nothing to prove that person wrong. She's not an expert multitasker, so she can't whine about her problems while handling her career perfectly at the same time. Her emotions affects her act. If she's sad, you can see it by how gloom and quiet she becomes, or how often she sighs. When she's angry, you'll see from how cruel her words is and how everything seems to be pissing her off. She does stupid things when she's emotional, like accidentally lashing out on somebody or abandoning her members or practise time when she's sad. Younghee does a lot and say a lot of stupid things when she's emotional.

Hard Working
Despite her being emotional, Younghee is a very hard working person. She hates it when people doesn't notice her hard work or acknowledge her skill. She works hard because she's afraid that people will hate on her if she fails. She's afraid that she'll be stamped as "The useless and talentless one in the group." so it's normal to see her practising her dance move even when it's past 1 AM in the morning, or how she constantly playing the same song over and over again on her phone to remember the lyrics, or how she's always the last to get out of the dance practise room. It's normal, but seeing her reasons, her reasons to be hard working, it's kind of pitiful. One should work for herself, not for the pleasure of other people.

Overly-Competitive
Competitiveness is good, but Younghee takes it to a whole new level. The girl is a perfectionist who puts 100% to her work, yes it's good. But when in groups, cases like Younghee scolds a member just because a simple vocal mistakes can easily happens. She wants everything to be perfect while sometimes, things just can't be perfect. She may be your friend and you may be her best friend, but she'll never forget the fact that you are another person she has yet to beat.

Kind Hearted
Oh yes, despite her flaws, Younghee is a very generous and kind girl. She helps other without thinking twice and is always the first to realize when you're in a bad mood. She tries to always be there when you need her, even when it's 2 AM in the morning and she's dead tired but you're still sobbing about the guy who rejected you, she'll try to be awake just for your sake. She's very polite towards other staffs and her seniors. She'd greet them when they walks past her and ask them how was their day and wishes them luck. And not just to the SM staffs, but also other trainees and strangers. Don't be surprised if you meet her on the street and you just have no idea who she is but she still smiles at you anyway, that's just her. Yeah, sweet, right? Her politeness however, will disappear once Kiriko gets to emotional.

Jealous
Yeah, she's very jealous of those who are better than her. As much as she hates it, Younghee hates to see people who are better than her, especially in things that are her forte, such as dance. She'll always try to find that person's flaw, even though she knows it's wrong and stupid, but the girl just couldn't help it.

Trivia :

Only, her chips didn't fall into the hole.

Instead, the chips was lying horizontaly, in a way that made it nearly impossible to get her chips. Frustrated, Younghee insterted another money and picks another chips. Well, she hoped that if another chips fell on top of her chips, the pressure would make her chips fell into the hole and she'd be able to get it. Turned out, the second chips fell on top of her chips but there wasn't enough pressure. So there were two chips lying lifelessly at the bottom of the vending machine. The other trainee realized her situation, some were laughing because of the hilarious position of the chips and some were trying to help her. One of the trainees that was helping her was him, Kim Jongdae.

Basically, Jongdae and his friends were banging the vending machine and after three minutes of useless kicking, punching and shaking, Younghee said that it's alright, she'd settle down with just kimbap or other food but thanks for helping anyway. Jongdae didn't look too pleased, maybe he thought getting the chips out of the vending machine was more of a challenge. So when Younghee turned her back from him, he gave the machine one last push. Younghee turned around at the horrible sound of body hitting a metalic surface and then... there was Jongdae, wincing a little because of the pain but in his hands was her bag of chips. "I got it!" he said happily before giving it to her.

After that, he introduced himself and the two became friends ever since. The chips became somewhat a symbol of their friendship, funny, but really, that Lays chips will always be a reminder of their fateful encounter.

1. Jongdae trolling Younghee by surprising her, she makes a very derpy face and he caught it on camera, for blackmail purposes

2. Jongdae and Younghee do a duet ;_; Younghee will play the guitar/piano, it's up to you
