I love the development of Hwa Shin by this episode. He was arrogant and self involved but now he's vulnerable and he shows that side of him to Pyo Na Ri. 

His action of switching her out was totally justified. I guess that was needed for her character to grow! :) Hwa shin grows more and more adorable in each episode. I kinda keep forgetting he has cancer. Bang ja's watch over Na Ri is also something i was waiting for.

Bonus point for Hwa Shin-Beum chemistry in all episodes! :* 

Looking fwd to the next episodes :D
