Company Workers

This episode was a bit boring, I found a hard time in order to finish it. Well, maybe because of theme but at any rate, the rare disease they picked was at least interesting.
I think Han will be introuble once they find out that he was looking up that case the prosecutor oppa brought to Kyung Hee. Even she's doing her own share of investigation which will bring her trouble at some point. What are those people trying to hide? Is it a mis-use of drugs and dangerous chemicals?
