Title: 5/5
Your title was meaningful.  If I were scrolling through the home page, there was a high chance that I would click on it.

Description/Foreword: 9/10
Your description was grammatically correct and simple.  Same thing goes for your foreword, which had no grammar errors whatsoever.  You could’ve added something else to make both the description and foreword more interesting, but you do have the basics down.

Poster/Background: —/10
None.

Characterization: 15/15
The way you portray the characters--the fear of admitting that they like guys, the bonds between the members in the band, everything--felt real.  

Spelling/Grammar: 18/20
For the most part, your spelling and grammar are great.  Under closer examination, there are a few comma errors here and there--nothing that editing can’t fix.  

Flow: 7/10
The flow seemed a little too quick--jumping from their twenties to their thirties to the end, when they’re both about ninety.  I wished you’d slow down a bit and add more details to the events happening.  Also, some chapters were a bit confusing, and I tended to rely a bit more on the summary at the bottom than I should’ve.

Originality/Plot: 21/25
The plot is a bit generic--two guys that love each other but are too afraid to say anything--but you’ve managed to make it into something a bit more original.  I, personally, wished that you had included more scenes showing the interactions between the members, even though this fic was a Jeongmin x Hyunseong fic.

Enjoyment: 5/5
For the most part, it was, indeed, enjoyable.

Total: 80/90 → 88/100

General Comments:
This probably wasn’t as harsh as you wanted it to be, but there wasn’t anything majorly wrong with your fanfiction.  I really enjoyed reviewing your fic, although it took me months to get started on it.  Thank you for requesting a review, and I’m sorry that I took so long trying to complete it.
