I think this drama is not for everyone. I eventually lost interest around episode 8 ish. It had a nice start and I was interested initially because I haven't really watched a drama where they show a fangirl as main character. The chemistry was wonderful between PMY and KJW. It was my first time seeing KJW and I was a bit reluctant and was able to warm up to him. I've watched a few romcoms and light/fluffy dramas and usually I liked them a lot. In fact I liked What's Wrong with Secretary Kim and it was entertaining. But this drama, didn't keep me entertained till the end. Halfway through the drama, I didn't feel like watching it. It got boring.
Ahn Bo Hyun and Park Jin Joo listed as main leads doesn't make sense for me. I felt like we didn't see much of Ahn Bo Hyun's story. They were more like support role characters to me instead.
I feel like they intended to show sarcasm around the fangirl concept. But instead it felt like they were promoting obsessive fangirl behavior instead. I think they should have been more clear with that especially since you see this behavior everywhere mainly in Korea with those sasaengs.
They also start revealing a lot of things near the end which one of it I figured it out 3 episodes before they revealed it. They did add more stuff to it later on, but it wasn't anything significant. I also had to skip watch some scenes in ep 15 and 16 because it got too boring and just watched what I wanted to watch.
If you wanna watch for romance go ahead. There's comedy, but as for a story itself I feel like there's nothing much to the story to watch it for.
