I wanted to watch this drama but I started with the first season because I thought that INR2 it would be a continuation of the previous one, although only one of the new couples was related to the previous plot. Anyway,I enjoyed with some aspects of this new drama like the no-ending relationship between Lee Jin Wook and Jung Yoo Mi and the intrusion of Kim Ji Suk between them, as well as the other secondary plots. What it let me down a bit was the incoherence sometimes in the development of the characters that it took realism away and it made of the whole a non-understandable and illogical story. In this way, I prefer the first INR which presented a good story-line and a lot of chemistry between the main lead actors. In the new INR, this chemistry showed up from time to time but I felt that it was strongest with the second guy, Kim Ji Suk than with Lee Jin Wook, who supposed to have the spotlight of the romance. For those who didn't watch any of the INR, I will recommend to watch first the 2 season, so they will be not disappointed when watching the first one afterwards.
