I did not really attempt to watch this, and I got through episode one and had a feeling that YooHan would not be here. And reading the other reviews, it seems I was right. The main reason I had wanted to watch season2, was entirely because I wanted to watch YooHan and YeonWoo's relationship develop, while solving the mystery of the disappearances.

While the mystery bit seems to be present, YooHan is not. And that is a huge no for me since there was no point for me to continue watching if not for their relationship. S1 left me hanging as I did not feel romantic sparks from them and I came for s2 for that, albeit there was sparks in s1 but I couldn't really say they were very romantic per se. I gave it a 7 so it doesn't affect the overall ratings that much.
