I'm writing this with only 10 chapters in, the premise of the story is interactions between an Idol and her only fan(she has no other fans) Concept: 7/10 Unique and so far well executed. Art: 8/10 Very expressive and clean. Characters: 7/10 Slightly generic and slightly original but still quite entertaining.Story: 7/10
Well paced sugar fluff, and the dialogues are a good use of use of words with consistent humor and sometimes extremely funny scenes.

Enjoyment: 7/10
So far so good, no plot holes, nothing to really complain about.

In conclusion you should give this manga a try and see if you like it (most probably you would), the chapters are short but mesmerizing so it shouldn't take much of you time.
