Pros:
Cute premise.
Leads did pretty well with their rolls considering.

Cons:
This story is really poorly done. A complete lack of intriguing plot, or even any plot whatsoever, is causing me to drop this at episode 4. Up to this point it's been nothing more than a mash of random slice of life events, it's so dull there are even entire scenes centered around the FL having casual and pointless conversations with strangers in street markets. Conversations which of course have nothing to do with the plot, because there is none apart from the extroverted ghost possessing the introverted weak girl. Other random scenes include cooking meals, kitchen staff goofing around with each other, even going on a tv show...all which lead nowhere or have anything to do with propelling any kind of story forward.

I've never seen a romance take this long to begin either, even at episode 4 their interactions are always: FL acting obnoxious and ML acting like he despises her, without even so much as a hint of romantic interest.

I've seen stills of their kiss scenes which have kept me watching hoping for chemistry, but I can't take much more of this.

Update: Well I ended up pushing through those first 4 episodes and by episode 5 it finally started to pick up. Episodes 5 and on are very good and definitely worth watching. This was such a strange slow start, I'd almost recommend not even watching the first 4 episodes, they're fast forward-able at most. The story now is really good and the ML is a great actor. Raising my rating to 9.5/10
