I can't understand why, most often than not, Kdramas tend to veer off course from the synopsis provided.

Trolley was one such drama. You would think that this would focus on the past of the FL, just by reading the summary. But as it progressed, other issues tended to overshadow it.

I loved the ML in Beautiful World because he truly has depth in his acting. I think he could have done a better drama than this one though. Trolley is s super slow one and there were characters that didn't need to be there. Soo Bin for instance. (Probably because I didn't like her in Revenge of others). Her face is always the same. Boring, actually. I don't know why she keeps popping in on these recent dramas. Would definitely not want to see her in other dramas. The assistant of the ML (the guy from Juvenile Justice), was also one such character whom I felt didn't contribute much. In the end, he didn't even pay for what he did.

The story is just mainly about passing a bill about deceased sex offenders. It is truly unbelievable how the writer dragged it on for 16 episodes. 8 would have been enough.
