The FL had no character development and the ML never tried to understand her insecurities so basically their relationship was baseless. If the writer had working brain cells she would have at least used their past to create a plot. I was expecting the ML to admit that he was the insecure one and has a hard time trusting her feelings because in the past she ignored him and moved on. But no instead everything is just in the air. Does he like her? meh sorta who knows. Did he like her in the past? meh sorta who knows. Also the book he wrote is ridiculous and doesn't mean anything to the audience. We can't read it, its not helping us understand him any better.

Cardboard characters, no development, no real plot, just angst and immature interactions. They all need therapy. That tsundere landlord needs to be checked for narcissism, sociopathic tendencies and mommy issues, ML has communication issues, probably depression and dysfunctional relationship with love, FL needs a confidence coach and self love. That blond girl although brain dead and slow, she's a cutie and can do no wrong so I'll spare her.
The actress who played the FL carried this drama, despite her character being a doormat and a masochist, she portrayed her perfectly.

Conclusion: BOooo, *throws eggs*

I don't completely regret watching it though, messy people are funny.
