Hi HelloKitty1006!

To begin with, if were to make your title grammatically correct, it would be, “Today, Tomorrow, and Forever.” What I got from your title, 2DAY, 2MORROW, & 4EVER, was that it was intentionally written in short cuts and all capitalized letters so as to make your story feel more fun and inviting. The former title is the proper and correct one (you don't see any printed books written the way you wrote your title) but I understand that your current one is more unique and it catches your attention easily. 

The poster that you are using is actually a banner so I suggest that you request for a poster in one of the numerous graphics stores that kindly offer us their services. Remember that your poster also reflects your story's theme and genre. 

Honestly, I got confused with your forward and description. There seemed to be so much going on. First of all, the part where it shows how Hyuna was accepted in Woolin Entertainment was not a description but a preview. You have two previous, one in your description and another in your forward. Too many can become confusing for your readers.  Also, the introduction of characters is usually put in the forward and not description.

There were some grammatical errors in your second description:

You and your best friend Kim Myungsoo had just become trainees for Woollin Entertainment. You guys have known each other ever since pre-school. Ever since then, you guys sang together, danced together, and dreamed about becoming a big star one day. None of you’s really had feelings for each other. “Friendship is more valuable than a relationship.”

You promised each other than nothing will ever come between your friendship. Little did you know, being a trainee is hard. You leave behind your family and friends. You have no friends while you are a trainee. That’s because you want to focus on your debut. Well, if you’re ever going to debut. But both of you still promised that no matter what happens, you guys will always be best friends.

It should be:

You and your best friend Kim Myungsoo had just become trainees for Woolin Entertainment. The both of you had known each other since pre-school. Ever since then, you sang and danced together while dreaming of becoming big stars. Neither of you had feelings for each other.  

“Friendship is more valuable than a relationship”

You promised each other that nothing would ever interfere with your friendship. What you did not know was that it was difficult to be a trainee. For instance, you must leave your family and friends behind. While you are a trainee, you lose companions because you need to focus on your debut. Well, that is if you ever debut in the first place. Despite all challenges, you and Myungsoo promised that no matter what happened, the both of you will always be best friends.

Note to remember: There is no need to separate these two paragraphs with a line.

Story

You had a couple of grammatical errors in your chapters. If you want to exaggerate a word, you can italicize or make it bold face instead of stretching it and making it difficult to read.

My only problem with your pace was that some of the descriptions of the characters were rushed and you introduced so many characters in one chapter that I started getting confused. Other than that, I liked your story’s development and pace.

Most of your characters are fine, but some of them are just too perfect. Take Hyuna for example. It’s impossible for a person to never get upset and angry. Also, characters that are too nice and perfect are very unrealistic and, in my opinion, frustrating to read. Everyone has flaws and characters in a story are no exception to that.

I find your plot unique and intriguing. I needed a little time getting used to the fact that you placed Hyuna and other idols in Woolim Entertainment, but I eventually got used to it and began enjoying the problems that she faced there :P

What I also found interesting was that you paired up Hyuna and L together when I would never have even imagined that couple together. Even if some people may not be as open to that couple as you are, I personally became more curious to read your story because of it.

Over all, I enjoyed reading your story and it is a pity that you decided to remove it, although I do understand your decision. It’s great that you are still writing and I hope that you never stop :)
