The story line for this drama was honestly amazing! Also very informative towards the disease. There are many dramas where they "sugar coat"it, but this drama didn't at all. Which I loved, this showed all the watchers the real struggles of this terrible disease. How it drastically changed the life of a young girl! You view the struggles, Aya goes through and it gradually increases. Also shows how it effects the family, the reaction and changes is very relatable to what any family would do. Though I didn't cry while watching this drama it left a mark.The acting of all the cast was amazing. The family's reaction and acting were superb. The expressions of pain and sadness were so realistic! The music matched everything perfectly especially the song in the trailer. I would rewatch this drama with friends, it's so touching and the message sent is very inspiring. This drama has actually got me very interested to the point where i want to read the book from this drama was originally based off.The flaw I found was there were sometimes that I skipped since they seemed like fillers. Other then that I have no other negative thing to say.
