Title: (4/5)

I think the title gives away too much, but it matches the vibe of the story.

Description/Foreword: (8/10)

The description is short and simple. It goes straight to the point. I like it.

There isn’t really a foreword.

I applaud that you didn’t describe each character. I like when the reader gets to know the character through the fanfic.

Also I think you should put some color, since there’s not a poster nor a background. Appearance is important.

Plot: (20/25)

The plot seemed really cliché until the invasion think came up. I was like WAIT WHAT? Really, it caught me off guard. It was very nice and got me really curious!

Grammar: (18/20)

Your grammar is really good, I didn’t find any spelling mistakes, but try to use commas more often. In chapter 3 you didn’t describe any setting just thoughts and dialogue, I’m not saying is wrong, but maybe you could improve it a little. I see in chapter 7, you started to use paragraphs and describing more which I think it’s really good.

Characters:  (10/15)

I think your villains are a little careless. I mean the plot against the twins was supposed to be ultra secret and Sehun found out really quickly, and Yunho and Yoona are supposed to be a secret couple, but they were making out at the sight of anyone. So maybe they should be a little bit more careful…

The good guys are awesome no complains :D

Flow: (10/10)

It has a nice flow. No complains.

Writing style: (4/5)

I like the way you describe persons a lot, but don’t forget about the setting!

Overall enjoyment: (9/10)

It’s a nice story, hope you update soon.
