First n foremost this is just my opinion.
I don't even know where to beging it started out great. It was weird, interesting and had funny moments then somewhere along the road things just got out of hand( not in a good way). The story flopped, the ending dragged like how do you drag a misunderstanding for like ten episodes! Disappointed with the middle and ending of it.

The acting was fifty fifty they did what they had to do but when they were to show some kind of emotion when needed they didn't .( Reverse reactions if I may call it).FL aargh like I don't even know how to explain it but wasn't my cup of tea. The mL at some point had dead pan expressions when emotions and reactions are needed. The supporting role at least tried their best but still couldn't get past the plateau of their acting.
OST was the only saving grace in this.

Overall, if they didn't drag it out for long, made some realistic misunderstandings and not over exaggerate them. The FL was just childish, Ml didn't progress, like the character development was just lacking something
