Where is the fluff?

I started watching this series just cause of Gong Yoo and perhaps a bit of fluff but every episode is just getting more and more serious. Life threatening illness is the flavor of the week, boy this show is getting more and more grim.
Great for Yoo to be able to show his acting chops but it is clear he is still just honing his talent at this stage. I won't say he has come a long way but the change is really pronounced.
Nice to see Gong Hyo-Jin not be as easily swayed as see seemed to be in earlier episodes. Her refusal to remove the ring even after Tae-In asked and her honesty about her feelings was refreshing. I am at the 43 minute mark on the episode and so far she has not cried this episode so that is also a plus. OH wait 5 minutes later and she is bawling...spoke too soon.
