Your Story is Called What?!:  ☠☠☠☠☠ 

Personally, I didn't like it. Not only seemed one of those 'I'm Living with --' kind of stories, but it just didn't look attractive. I pretty much already guessed the biggest surprise of the story without even looking at it. 

So this Thing Right Here...That's a Description and a Foreword...? You've Got to be Kidding Me!: ☠☠☠☠☠ 
I must ask for you to be very careful when writing your description. If the title manages to lure the readers in, the description is like a little taster of your writing. If it isn't right, the readers won't continue. The problem with your description was that you told just way too much. I mean, I was practically already reading the actual story. Also, you changed grammar quite a lot. Also, you used the wrong words at times. That didn't help, either. For example:

Knew [ Wrong ]

Found out [ Right ]

Your little foreword did not help at all. I am a big Eunhae shipper, so I pretty much know quite a lot about the characters already. When I saw your foreword, I was like, 'Seen this before. Should I skip?' But I couldn't, because I had to review your story. The line that slightly put me off was,

Flirtatious fishy.

What? It was just so out of place.

I'm Ready To Stab Your Characters Now:  ☠☠☠☠☠ 
They seemed like such cliche characters. Donghae; the bad boy. Eunhyuk; the nervous wreck (in a way) or the weak one. Minor Characters like Kyuhyun; plain. Some of the characters seemed very unrealistic. The girls at the club weren't very realistic. Quite forward, a bit too much as well. Also, the way how Donghae is acting after a simple relationship is rather overreacting, right? From what I saw, the relationship wasn't much.

I took off points because of unrealism, the character profiles in the description and that fact that also their thought process was awkward to read. 

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

Well, I had never really seen this kind of fic before. But nonetheless, I cannot ignore the unrealism of it. There are many questions about it that I just need to ask.

Why did they make up that weird contract?

What's up with donating all the property to the poor if the child refuses?

What's with making the contract before the children were born?

Why didn't they think that the children weren't going to be both girls/boys?

Why don't they just break the contract?

Breaking a contract is possible.

There were a few weird things that happened here and there, but even those were cliche.

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

Your grammar consistently changed tense and because of the certain situation you were writing about, I couldn't get into the story properly. It was just awkward for me. Your spelling was actually fine, but the grammar was just too much to dismiss. Also, your punctuation as well.

"Blah blah blah?", [ Wrong ]

"Blah blah blah?" [ Right ]

You don't need that comma. 

.. [ Wrong ]

... [ Right ]

An ellipse has three dots.

"Blah blah blah." she said [ Wrong ]

"Blah blah blah," she said [ Right ]

"Blah blah blah?" she tapped her chin.. [ Wrong ]

"Blah blah blah?" She tapped her chin. [ Right ]

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

Your poster did not match your story. If I saw it, I would've thought that it was going to be some angst/romance story. But your story seemed more on the funny side. You had no background, but I won't blame you for that. Your font was readable though, so good work. 

*YAAAWNNNN* Meter:  ☠☠☠☠☠ 
This is my personal opinion, but if I ever came across your story, I wouldn't have read it. I have been on AFF for a very long time, so my reading range has changed over time. The main reasons were because of the cliche plot and grammar.

I won't say if your story is worth readiing. I strongly believe that it is not my place to tell you that. You are the judge of your court. You make the calls. But please, try learn from this. 

VERDICT: ☠☠☠☠☠/☠☠☠☠☠
