Title: 5/5

The title obviously fits the story, and you're not ging to find the same title every day, so I give it a 5/5

Graphic: 2/5

- The graphic is beautiful, I just don't know if it fits the story well. For one, it's just three pictures of Kyungsoo, and I don't think they relate to any of his characters during the days. Even if it was just a numbers game-- four pictures, however random, is better than three for the "four" part in the title. The bottom of the poster gives it that "movie poster" effect, but you can't read the text and, because the fic isn't about a movie or something similar, it doesn't fit either.

- Each chapter image, too, could fit the chapters better.

- And because they're technically images, there are way too many pictures/gifs in your author's notes, adding to an already long length, and taking away from that "I just finished another chapter" feel.

Foreword/Description: 14/15

- omma should be umma or eomma (the direct romanization of 엄마)

- a whole bunch of pictures/images; it takes a while to load on mobile and makes it unnecessarily long -- just the names or one picture will suffice

Plot: 28/30

- i've never read something like this before, and it's pretty great, so yay? //imsoawkwardsorry//

- but at the same time, I feel that the story of each pairing could tie into the others more, to tie the whole story together at a point other than Kyungsoo

Characterization: 13/15

Although all of the characters are pretty different, I get that it's changed for the "crack" theme, so there's not much that I can say other than, yeah there are some characterizations that are off.

Grammar/Spelling: 18/20

This is pretty good, other than a few minor errors here and there an changes in tense -- I suggest you go over to correct them. You tend to overuse semi-colons, too, so try to lessen up on that.

Examples:

-That night, the twelve boys of EXO file in their apartment and proceed to lie down everywhere

should be "That night, the twelve boys of EXO filed into their apartment and proceeded to lay down everywhere." (lay and lie can get confusing, but lie is used without an object - "I lie down" and "I lay down on my bed" and there's a semicolon/dash/something to continue the sentence that says that they lay down on tabletops, etc)

-Nobody asked him to do it; nobody ever does, really. But he makes it a point to care for s. He dragged each one of the sleeping boys into their respective rooms and tucked them in.

corrects to "Nobody asked him to do it, nobody ever did, really. But he made it a point to care for s [etc]" (the rest of the quote was just to confirm the past tense. if it's wrong, I apologize, but then you should change them all to present.)

Overall Enjoyment: 6/10

It was good, I'm not gonna say otherwise. But one thing that was distracting and off was your spacing: there's too much white space, and a new line shouldn't be used for every sentence. Here's part of Day Five:

“Psssst. Go talk to him or something” Sehun had told BaekYeol. [delete this space] “You guys are in charge of him today, remember? [delete this space -- as long as it's the same character talking, it goes on the same line] Go play with him~”

[this is two new lines, you only need one]

Baekhyun just sighed, and mumbled a “fine…”

But Chan Yeol’s eye was twitching in a rapid motion, together with “no way, I am NOT going near that freak of nature. I didn’t want to take care of him to begin with.”

Baekhyun glared at him. [delete this space] “So, what? You want me to handle him on my own?”

Chan Yeol just stuck his tongue out. [delete this space since it's Chanyeol talking] “You expect me to cooperate? Really? [delete this space] After all the times I had asked you to put away your eyeliners—which you never did—you expect me to listen to you? [space] No. [space] Absolutely not. [space] I don’t care if I’m assigned today. [space] Maybe I’d consider helping if it was anyone else, [double space, double no] but fact is, I’m assigned with you. [space] And Baekhyun [space] I hate you, if that wasn’t obvious. [space] So good luck doing this on your own.” [triple space] Just like that Chan Yeol left—heading to his bedroom.

[one last thing, Usually Chan Yeol (or any name with two characters - Baek Hyun, Lu Han, etc) the names are written (in romanji) together: Chanyeol, Baekhyun, Luhan, etc.]
