Major spoilers ahead:

So the gist of it is that the FL and her mother have been locked away in a section of a hotel room by a Chairman. Seul Bi and her mother possess powers similar to that of powerful psychics. They're shamans of prophecy. They can see into someone's future by physical touch so Seul Bi and her mother always wear gloves. The Chairman uses them to see into the future so that he can make wise business decisions which he profits from. He basically keeps them locked up as his personal talismans. So in other words, Seul Bi has never been "outside" the real world. She grows up practically as a prisoner in a lovely "home" with her mother. Her only knowledge of the outside world is through books but the only books she gets to read are basically children's books and animals books. They cannot contain any stories regarding law, economy, politics, sociology, or psychology.

It so happens that the Chairman's son, Min Joon, had some friends over while his father was away. Su Gwang was his best friend and by coincidence, Seul Bi sees him through a door. Of course, besides those that know about Seul Bi, Su Gwang is the first man she sees and she immediately thinks of him as her "Prince". (Seriously?!) Seul Bi manages to escape because that "secured" door somehow magically opens. She sneaks out and spends a day with Su Gwang. Later, Su Gwang takes her back "home" to the hotel where he first met her. They are confronted by the angry Chairman who accuses him of kidnapping and he goes on to destroy Su Gwang's life.

Su Gwang survives being murdered for knowing about Seul Bi and assumes a fake identity. Two years later, Seul Bi escapes again and the first person she runs to is Su Gwang and she imposes herself on him.

I really don't know what to make of this show. There's something disturbingly annoying about seeing a woman who has the knowledge of a 10-year-old but the hormones of a 30-year-old. Like, what kind of creep would get together with a woman like that? It's almost pedophilic. Even the people who work around Su Gwang call Seul Bi "slow" and that didn't stop one shop owner who took advantage of her by telling her to buy stuff from his store with a credit card she found. Even when she had told the shop owner it wasn't her card, that still didn't stop him.

It's hard to watch a grown woman acting all "naive" and "immature" but yet pouts and pines after Su Gwang like a teenager. They're trying some twisted "A Little Mermaid" storyline in so far the FL uses a line from the book. Then she falls in love with the first man she saw. We're supposed to believe she's never seen the outside world but yet she manages and fares rather easily. She's supposed to be 21 but looks like a 30-year-old. Her character doesn't look 21 at all. And she's supposed to have the knowledge and persona of a child. We constantly have to see her clapping and acting with like childlike innocence, with wide doe-y eyes. Then we have to see her sulking after Su Gwang, as she openly calls herself his girlfriend or future wife. It's all so repetitive that it's not even charming or cute anymore. Then it's worse when she gets drunk for the first time and kisses the ML. It's like giving a kid alcohol and forcing her/him to drink it. IMO, that is the worse "first kiss" trope. Where the girl is drunk and she kisses the sober guy. Kdramas gotta stop romanticizing that crap. There's nothing cute or romantic about it. It would be far better if a sober man immediately rejects a drunk woman's advances no matter what she says or does. That's just being a true gentleman. Kdramas just skirt this by having the guy always taken by surprise.

There are other annoying things that I'm not liking about this show. The gangsters are idiots who look like they belong in the 70s, the neighboring shop owners' stories are boring and it seems like everyone is looking for Seul Bi. At one point, they show just how powerful Seul Bi's mother really is, and yet all this time, she didn't escape with her daughter?? Whatevs man. It seems also that the main lead Su Gwang is just oblivious all the time or clueless.

So far the only character I really like is Min Joon, the Chairman's son. At least he always wanted Seul Bi to have her freedom since the beginning. He seems nice so far but I don't know if he'll change. I actually wished they wrote him as the main lead or endgame. So far I'm on Ep 5 and already, I'm constantly pausing it to go do other things and then I come back to continue watching. It's not really holding my interest. I feel like the actors are lacking. It's missing something.

Update:
By the time I finished Ep9, I was losing interest fast. Took about two weeks before I started on Ep10 and I made it only halfway. It's just getting too draggy and uninteresting. There's no consistency with the FL. She's all over the place, one minute she's naive, and another minute she's like, I'm just gonna be a fortune teller and make money. I don't understand why her character would want to do that knowing what she and her mom went through. I also feel like the market ppl are very two-faced to both leads, IMO. The storyline is moving in all different directions and it's not even interesting. Watching the two leads be depressed is boring too. In other words, I'm realizing I don't care for this show, period. I'm dropping it for now and maybe I'll get back to it when I'm really bored and to pass the time. I've changed my rating from a 6.0 (from EP5) to a 4.0 (as of halfway through EP10) but it could change again if I ever finish this series.
