1st of all I don't really get it why people are rating dramas so high these days? The same case for this one as well if I'm not wrong.

The story was slow paced, scenes were stretched for no reason and story felt shallow as it progresses.

For better experience watch at 2x, skip the middle and watch last few episodes you won't really miss anything. I hate the fact that the writers are trying to convey the message by theme rathar than characters themselvess. Only watch it if you're bored to death.
