I enjoyed reading this webcomic, but let's be honest - there wasn't a whole lot of plot or character growth going on.
Story: Switched back and forth between filler/side stories and advancements to the main plot lines (in which Yusen continues to gain more bad press despite his best efforts, the two popular Kpop bands vie for the top spot in the rankings, and a new and upcoming band enters the world of showbiz). Normally, filler gets on my nerves, but in this manga I found it to be really funny. It didn't advance the plot, but it at least allowed you to gain a better appreciation for the characters. The plot itself, while not terrible, was also not anything original. It did have less drama that other, similar "showbiz" style manga that I have read - the rivalry between the two bands was pretty straightforward, and was approached from a more comedic stance. The story did have a rather abrupt, if cute ended. I got the feeling that the webcomic was terminated early, for whatever reason.
Art: Pretty generic webcomic style. For the most part, not noticeable as being good nor bad. I did find the "on stage" preformance scenes to be well drawn.
Characters: Endearing, if a little two-dimensional at times. There are some very strong hints of shounen ai throughout the story but nothing ever comes of it. As mentioned earlier, the story seems to have ended too soon - I felt like there were a lot of opportunites for the characters to grow and for their relationships with one another to develop that weren't explored.
