This drama is just different characters standing at different locations and talking non stop. There is nothing happening in any of the episodes but just non stop talking, being portrayed as some sort of philosophical stuff whereas in reality its all meaningless if you watch this till the end.
This drama gives similar vibes as What's wrong with Secretery Kim. But this is a sort of drama which is good while watching, yet you wont remember even one scene or OST once it is over.
