Park JinJoo's character made an ominous statement: "a developmentally challenged illustrator working with an emotionally challenged writer will either be a huge success or a colossal fiasco".
The latter turned out to materialize.
The plot is a mess, and I highly praise the actors for being able to survive it.
Personally I hated the clothing of the FL, though I understand that other people may have loved it (apparently it's expen$ive stuff).
Not everything is a disaster, though. Here and there the author shows that she can - perhaps if she wants and/or perhaps with more experience - do good stuff. For instance, in the early episodes there were some interesting events, like the woman wanting the guy and thinking she is holding him in her hand. It was very well done.
