This review is posted LATE on my (momodays09) part. The reviewer, hopexdreams, actually had this done a long while back in late May but it has taken a while for me to post it due to my hectic schedule. I deeply apologize to both my reviewer and the requestor. All in all, I hope this review helps you and please don't take it out on hopexdreams. If anything, take it out on me haha...Thank you!

Title (4/5):
There are several stories out there with pretty similar titles, but yours was one of a kind. Based on the story, the title fits the story and relates to it well.

Appearance (2/5):
Although you don't have a poster nor a background, all that matters is the quality of a story. The chapters seem a bit messy to me as there were many conversations, leading to the frequent usage of " " and after each " ", there will be several sentences that come after it. With that being said, it makes your chapters seem slightly messy.

Foreword/Description (5/10):
Your description was intriguing, but there should be a full stop after each sentence. The "MiYeon loves singing. Nothing was better than singing to her but her dream on being a musician was destroyed by a disease and she hides this from her close friends. When all hope is lost, she has to face surgery. But before separating with the boys, a lot of drama is stirred and she has to fix all of this. Will she be able to do all of that? Or will she rely on her best friend through all of this? 

On a side note, her best friend has been through much suffering that she must protect her from being hurt again and again. As a best friend, can she do that too? " part wasn't necessary, in my opinion. It seems as though you gave out too much in the description itself.

What the description could've been ::

He loves the way her voice resounds through the whole room.

She loves the way he was always worried about her.

He loves the way she smiles as she reaches every note.

She loves the way he always makes her laugh.

He loves the way she enjoys singing even more than he does.

She loves the way he harmonizes to her every melody.

But what if she stops doing the only thing she loves?

But what if she needs to avoid being around him? 

"I have a song I'll never sing but it'll stay in my heart. While he doesn't know I like him, my feelings should be silent like that song. It's better this way right?"

I'm not sure if it sounded better that way, but it's just a simple suggestion. Having an author's note as a foreword is completely fine, but you should've typed 'A/N :' before you begin writing your author's note. Other than that, your description was well written.

Plot/Storyline (14/20):
Your plot is not common, but for some reasons, I can never get bored of these type of plots. /lol/ However, despite the angsty description, Mi Yeon seemed too cheery although she was leaving very soon. There should be more sad thoughts of her between the conversations, instead of the thoughts being the last sentence of the chapter. Other than that, your plot was interesting and your story was good!

Character Development (24/30):
Mi Yeon and Hyo Ri seem to be two typical best friends who play and joke around all the time but they know when to be there for each other. Their characters are developed pretty well. However, you said that EXO were the school's popular boys. Nobody seemed to be like.. looking at them or cooing in their direction or something. They just seemed to be a normal group of /good looking/ boys in a school with some female friends. The character development was fine though.

Use of Language / Mechanics (18/20):
I don't know if it's me, or you seem to be a native speaker. I can barely find any mistakes in your story. There might be some misplaced words here and there, but otherwise, your use of words and language was excellent. It was easy to understand and no words felt wrong in any places. Great job!

Flow (9/10):
The chapters were slightly long, making the story seem a little draggy. However, after rereading it, your flow was really good! Nothing was rushed, and nothing was too repetitive and boring. Most stories seem to be a little rushed or draggy, but yours was amazing. Keep it up!

Reader's View/Enjoyment:
The placement and the spaces between each fragment of a chapter was a bit odd, causing the story to seem a little messy with all the dialogues. However, the story was quite enjoyable. Having a poster and a nice background for the story will be great help to get more readers to read your story. I'll also suggest not writing the OC's names like HyoRi and MiYeon as it could annoy the readers. It'S LiKe ReAdInG LiKe ThIs, literally. In my opinion, it should be either Hyori/Miyeon or Hyo Ri/ Mi Yeon, but not MiYeon/HyoRi. It irritates the eyes. Besides, if you were to use romanized words, making sure that you use it the proper way is important as some readers might get offended. As a prime example, “Baboya…” in Chapter 1. It should be "Babo-ya...". Lastly, /I know I'm not supposed to review what you typed in characters, but/ I don't think there's a need for "EXO EXO-K EXO-M Lay Luhan Kai Chanyeol Baekhyun Suho Sehun DO Xiumin Kris Tao Chen" in the Characters. It could've been summarized to EXO, Choi Mi Yeon, Lee Hyo Ri. Other than that, your story is very enjoyable.

Final Score: (76/100)

Additional Comments:
I'm really sorry if you didn't like the review or it didn't help you! Your story is really good, but you just need to make it look neater. Other than that, your story is really good. Looking forward to read more of your stories!
