Disappointing 2nd season

First of all I was so confused by Jiwoo's total switch up, he always was more reserved but this was too much and I didn't feel this treatment was justified even after seeing why he did what he did. This season felt like it dragged on for too long and it couldn't make me care about any of the side characters. The story wasn't too interesting either, just very simplistic alike other kbls. The chemistry between the leads was still great and I was still happy they ended up together in the end.
