Okie to start the review off, the summary is only a very small part of the story that will eventually be insignificant and may lead to not liking to further plot because of expectations so here might be a more detailed summary:
Ha Ji was bullied by her two brothers that were learning karate and fencing at the time and she turned to Te Hu who called her a puppy that always need help. Determined Ha Ji learned all the martial arts possible and became a jjiang at her current high school. Soon after a motorcycle incident happens as they were going to conquer another territory and she "died". After some misunderstandings and supernatural power involvements, she ended up in a perfect body and met her other half. Through halfway the whole series she goes back to her body and her sub-jjiang Han Seo is now in major play as a love triangle forms, revenge, betrayal, and trust is now in play.

Story: Since the summary is up there, the story is pretty much describes but without all the drama in between. Overall the story is pretty well planned out and I liked how the artist ended put some lame-ass ending when a person died and continued with how their future turns out therefore 9. And I like how she didn't add supernatural elements everywhere just so the story makes sense.

Art: Like any other manhwa art, it is partially detailed with main characters and just so-so with the not so important characters and sometimes it just makes you pull your hair out that they don't care about very insignificant character resulting lookin kinda unbalanced. Either way I can't draw like her and all the others so they definitely deserve a 8.

Character:(JUST IN CASE THERE MIGHT BE SPOILERS) The best thing possible in a manhwa/manga. This is absolute brilliance in the last half of the manhwa even though the first half was good I fell in love because of the second half.
The main character in her own body in the second half of the manhwa definitely showed all her embarrassing moments that are also hilarous but most of all the question of wickedness comes into play. It is revealed that she is not simply just "another airhead", she knows everything that is being played around her but she acts oblivious to it and just watches. A true emblem of a human being, but I seriously thought that it was her nature to want to watch but I was proved very wrong when I discovered she like other humans also can't let go and was moved not by trust but greediness. I absolutely fell in love.
Then Han Seo, a guy who fell in love with a toy (Ha Ji) even though he knew he should've stopped when he got the chance, he didn't instead he got crazier. A true psycho in the story, he solved problems through violence and a bit of intelligence. He laughs mostly from Ha Ji and due to her trusting nature he couldn't let her go and was even willing to "go to hell together" with her if she kept her trust and didn't choose. A sad guy who fell in love to unrequinted love that even he knew but still couldn't end it. The only character that puzzled me and kept me interested in continuing.
Other main character are also very interesting like Aram who loved a guy who totally told her off but couldn't give up until she discovered that feelings could be changed. Sin Uoo even though he's the main guy character I never really felt good with him. He's nicely done and everything but I can't feel depth into his nature so ya you gotta figure him out yourself. Jeong Hyeop a totally loyal character to Han Seo. He also acts as an advisor for Ha Ji and tells her advices and urge her to make decisions and treats her like a little sister. ABOSOLUTELY 10.

Enjoyment: Overall the story plot and characterization I can't not enjoy it but it wasn't really the best of the best out there but since writing a review I found out that I actually enjoyed it very much so therefore changed to 9.

Overall: 9 :)
