It's honestly a shock how intelligent Eunhye is in both worlds; in once she's a talented lyricist, and in the other, she's a very smart engineering student. Of course, you need some context for her intelligence being shocking; luckily, that's not hard to give. For a leader, she's kind of a weak person; the younger/other members of Reverie push her around in the idol world as much as they do in the expected world. She has no authority over them - it's like she's a really incapable babysitter and the kids are running around her all crazy-like. Really, the only reason she's the leader is because she's one of the oldest members, and the only reason she's considered the thread in the expected world is because she was the one that needed roommates to help pay for her (large) apartment. Unless she's in her element - engineering in the Expected World and writing songs in the Idol World - she's really kind of useless, because nobody's usually listening to her. She's a complete and utter pushover; she'll try to say things and nobody listens to her. She'll try to suggest something, and she'll either get ignored or dismissed. She doesn't command respect like a lot of leaders do because she doesn't want to be seen as pushy (Eunhye cares a lot about what other people think of her). As I said, she's pretty smart, though; she almost lives in her head and is always thinking up new ideas. It takes a lot for her to share said ideas, but when she does, your first response is pretty much always "Why didn't you tell us earlier?"

And, I mean, she's got more good traits than just intelligence. She has the unique ability to see what's loveable about everyday life. She's not the kind of person that wakes up in the morning, brushes her teeth with alchohol and proceeds to destroy cities, or anything. Rather, and despite not being a morning person in the slightest, she'll look out the window and see what kind of day it is. Snow, rain, sunshine, doesn't matter; she'll find something good about it. If it's raining she'll think about how crops and such need water to live, etc. She's not the kind of person that sees joy in everything regardless of if its bad points outweigh its good ones, but she can find little pieces of happiness within the dark things and she much prefers to focus on those. She's also very respectful; she judges individuals as individuals, rather than judging them as part of the groups they belong to.  Lastly, when she is in her element - be it performing or building something - Eunhye shines. She's a completely different  person when that happens; all of a sudden, you're wondering why you don't usually listen to her. She's so different otherwise that it's almost shocking. She isn't the type to approach people when she's finished doing something she loves (or in general, actually), which is fine; a lot of the friends she makes are because people approached her and became attached to her weak side.  

She's the middle in a set of triplets - Lee Seuk Hye, Lee Eun Hye and Lee Soo Hye. Her eldest sister is too uptight, her younger sister is too spoiled, and Eun Hye herself is too much of a pushover - which is probably why the three get along so well. They were born and raised by their mother and father, two restaurant owners, in Seongnam, South Korea. She lived a good childhood; her sisters were her best friends, and in the Expected World at least, Eunhye prided herself on getting the best grades of all of them. She realized she liked girls in high school, when she realized she had a huge crush on her then-best friend. That is where her story begins to differ.

In the Idol World, she came out to her parents; bad idea. Her sisters were totally okay with it, of course; they'll always support and lover each other. Eunhye was about 17. Her parents kicked her out of her house and forced her two sisters to stop contacting her (although they still did so in secret). In order to have a place to stay - the trainee dorm, specifically - she auditioned for Cube Entertainment, staying there for two years before becoming a trainee and eventually debuting in the girl group called Reverie under Jellyfish.

In the Expected World, she stayed in the closet, graduating high school at the top of her class and entering university with her sisters. Rather than living at home with her parents, she decided to rent a rather larger place to stay. She needed help paying for it and decided to accept roommates - to be exact, six of them. She majors in engineering, while her two sisters study political science and broadcasting respectively, and has dreams she can almost remember every night. 

IDOL WORLD. Jung Eunji - main vocalist and one of the most internationally popular members of A Pink. She's fiery, funny and takes no from anyone (which, actually, is true for both worlds). The two met while Eunhye was still a trainee under cube; Eunji is two years younger than Eunhye, but they hit it off and became best friends right away. She's always trying to convince Eunhye to develop more authority over...well, everone, which doesn't always work. Eunhye's a lot closer to Eunji in the Idol World because they trained together for two years, and Eunhye is also very, very carefully hiding her crush on Eunji. Especially now that they're idols - a gay scandal would kill both of them, like, ten times over. They still keep in touch and are known to be very good friends.

EXPECTED WORLD. Jung Hyerim, on the other hand, is the daughter of one of Eunhye's professors, who's training to be a vocal coach. They've met exactly once, but it was probably love at first sight for Eunhye. In that world, A Pink is a group of fairly popular yet very  nice girls on campus (although it's no secret some of them are in high school), while Eunhye is a back-of-the-classroom type of engineering student who's only really good at one thing. Until her professor brings Hyerim in again, they probably aren't going to meet, unless they run into each other on campus or something.
