So rushed.

They should have given the whole sick-baby plot less time, and used that to develop the cancer plotline a bit more. It feels careless how they did it. Like it was a last minute decision. Also, for such an aggressive cancer, either Eun Jae's treatment was very conservative or she was extremely lucky not to lose her hair. Just put a head scarf on her, a little white make up and make her look actually sick.
