This drama main problem is that it wants to be deeper than it is.
So in order to appear as mysterious and artsy as possible it throws us viewer in the middle of the plot without any explanation and keep being vague enough.
Character introduction or their motivation – nope - puzzle them yourself from what you can observe, maybe then they will make deeper sense.
So we have three main characters that storyline joggle from person to person with time skip – making one confusing start of drama.
But okay middle part for sure will clarify it for everyone, right? Nope.
What big crime Cha Jung Woo commit to be banned for writing under his own name? Everyone speaks of it in such vague manner that its just scream that script wants to appear more than it is. In days of digital printing and self-published book this whole storyline just don’t make sense the more you think about it.
Making main points of storyline vague doesn’t make drama artsy or deep.
As for romance – just forget it. Leads don’t have chemistry, their romance plot line is not cute or believable they just woke up one day and decided – Oh I want to be with that guy.
There is nothing memorable about this drama – maybe except this song they use.

Overall I watched worse dramas but also many better ones.
If this drama didn’t pretend to me more than it is – it would be a much better experience.
