Title: 2/5
It's not original since there are a lot of stories with the same name. The name suits the story however since it's about her falling in love with her best friend.

Foreword an Description: 8/10
I think that the first couple lines were good, but when you got to the part 'She felling in love with her best friend Kai...' I think that last part gave away a lot about what was going to happen in the first couple of chapters. The foreword was nice and I really liked he layout. You creditted everyone properly and it was great. 

Characterization: 17/20
Hayoung is a very strong character and she stays that way through out the entire story so that's a big plus. But since Jongin is her best friend, he's been her best friend even though he has been dating Krystal. But then when he tells her, he abruptly doesn't do things with her as much and it's so shocking and abrupt because of the sudden change. Kris' character is cold but it seems like he's a softie on the inside! I really love Kris' character. Krystal seems so sweet but ugh her character! You've made her into an ideal character that is consistent throughout the story.

Plot: 13/20
There are so many stories like this one, a boy is a kingka, he has a best friend who is the opposite gender. Then she falls in love and he's dating someone. A new boy enters the story and he gets jealous. It's not very original and I guess you could put it as a typical story on AFF. But since Luhan entered the story, it's been really interesting on the reactions and everything, so props for that plot twist right there. The flow was the right amount however and made the story's plot more descriptive and interesting.

Mechanics: 2/5
Your grammar was good and so were your tenses. The punctuation was spot on in my opinion. There was just one small slip. '" Don't punish a bad by being a bad. Punish a bad by being good. "'
There isn't really supposed to be a space between the quotation mark and the next word. The correct form is '"Don't punish a bad by being bad. Punish a bad by being good."'
I saw plenty of spelling errors however.
You use the word 'door nob' often. The word 'nob' is actually spelled with a 'k' in front. Therefore, it's supposed to be 'door knob'.
Also, in chapter 5, before the split, there was the line 'I did't! I ccouln't!' Those were both wrong. The correct way is 'O didn't! I couldn't!'

Reader's responses: 5/5
The readers are very much into your story. They root for both Kai and Kris. They know that her lie is messed up and are waiting for you updates so good job!

Enjoyment: 8/10
