I had a pretty good time up until around episode 12. I mean sure the writing is pretty sloppy throughout, but the variety show concept and the fluff were nice. The leads had reasonable chemistry and quite a few cute scenes.
The second lead stories were annoying, but luckily I found them easily skippable.

Chan Sung as a cartoon villain did not work, then again can I really blame him under performing, when it was such a badly written character?

Ultimately why I decided to rate this show at 6/10 is due to the last two episodes. This is supposed to be a preproduced show, but the writing resembled live writing during the last 2 hours, you know when the writers keep stumbling trying to save the bad ratings or at least make a token effort.. People in the comment section here praised the drama for not breaking up the main couple, well I'm not sure if I can agree with them. Episode 15's script at times made me feel like they were separated for like 2 years, then after a short reunion they went into another 3 months of pseudo separation in the final episode. Perhaps it's just kdrama fatigue, but the separation(s) made unusually little sense to me, even if I compare this drama to something like This is My First Life. So yeah, the 10 minutes of happy ending before the rolling credits did not alleviate the bad taste in my mouth.

I cannot stress enough how good the variety show with the antifan idea is, unfortunately they did not expand on that enough. It could have been something really great, oh well..
