So apparently, someone can be in a coma for decades, wake up in a few days, and immediately pull off a murder and bury a body deep in the woods. And apparently, the final victim of a notorious serial killer - whose husband never stopped looking for her - can just get stashed away in a mental institution by some random human trafficker and no one cares. Hyun-soo’s still an idiot for hiding things from Ji-woo, and she’s just as much of a moron for still doubting him after everything that happened. This is frustrating for an otherwise good k-drama up until this episode.
