Definitely interesting plot but at slow pace

I truly enjoyed watching s2, s2 is better than s1,
It was funny to see dong-mi and ami fights and the professor ?? definitely the end that he deserves...ep 16 end is like wth..curious to know how they all ended up in that way...though the story line is good but im not sure if its fault of director or story writer...the story plot was told to users at a slow pace S1,S2 could have been combined into a single season. S1 first 8 eps are tooooo slow and not much story in it. Hope they'll make S3 worth all the time i have spent watching it.
