Your Story is Called What?!: ☠☠☠

The title is relevant to the story and grammatically correct. However, I’ve seen quite a lot of these titles around. It somehow bores me when I see this type of title.
 

So this Thing Right Here...That's a Description and a Foreword...? You've Got to be Kidding Me!
☠☠☠☠

The first thing I saw was a sea of blue?! Sorry, it just made me yawn. If you want to highlight the whole paragraph in blue you might as well just leave it as it is. Just a personal suggestion, highlight the key points in the paragraph in appropriate colours to attract readers’ attention.

 

As for the language,

Wrong: haitus
Correct: hiatus

 

Wrong: fufills
Correct: fulfils

 

For the foreword, there are pictures attached to the names of the character and their schooling status. However, it is too simple and spacey. You also slightly explained Block B’s behaviour in general, which I figure that it will be better if you reveal it in the story itself.

 

Language-wise this time,

Wrong: As the story progresses you’ll learn more about every one of them.

Correct: As the story progresses, you’ll learn more about every one of them.

Remember, a comma can make a lot of differences.

I'm Ready To Stab Your Characters Now: ☠☠

Characters are definitely different from the typical ones. Block B is defined as playful and I can really see how playful they are. How Cassie is not a hardcore fan of Block B surprises me, a pleasant surprise actually.
 

Are You Sure You Know What You're Doing? ☠☠☠

Until now, the plot is just developing so I cannot say much, but isn’t the flow too slow? And I think that there is a loophole. When students register for a school, doesn’t the profile has their picture too? How did they managed to trick the school management about their names? That is what I do not understand. Other than that, the plot is developing fine.
 

Better Stay In School and Listen to your English professor: ☠☠☠

Generally, the language is fine, with some mistakes at times. However, you make it awkward to read by ending the sentences weirdly from time to time.

Examples:

What you wrote: I brushed my teeth while trying to fix my hair. I failed miserably. (Chapter 1)

What!?!,,

I will actually suggest you to write it like this instead: I brushed my teeth while trying to fix my hair, which failed miserably.

It actually depends on how you see it.

 

Other examples of fault in language (A/N: I’m not listing all.)

(Chapter 1)

You wrote: There that looked better.

Correct: There, that looks much better.

Since it is actually an inner thought, you can differentiate it from the others by italicise the text. This will make it clearer for the readers.

 

You wrote: lastest

Correct: latest

 

You wrote: I don’t mind Principal Lewis.

Correct: I don’t mind, Principal Lewis.

 

(Chapter 2)

You wrote: They already had enough trouble in Korea, as it was.

Correct: They already had enough trouble in Korea.

I don’t think the last 3 words are necessary. However, it’s your choice.

 

There are more, but I don’t want to probe on it so these are some mistakes you made. After reading through, I realised that your sentence structure skills are not that good so perhaps you can work on this area. 

I Can See Why You Like Writing Better Than Arts: ☠☠

The poster and background are great. They are suitable for cheerful, fluffy stories like yours in this case. However, I think that it might be better if you used colours that are more cheerful than just blue. Examples are perhaps yellow since Block B has such bright and playful personality. The font and colour are fine. 
 

*YAAAWNNNN* Meter: ☠☠☠☠
The flow is a little too slow for me, so it actually kept me from getting engaged.

VERDICT: ☠☠☠/☠☠☠☠☠
