I finished watching the drama up to episode 16, I was 7 years late. The last episode broke my heart, especially when Geum-Bi is on a near-death experience with Death and Mr. Fox, and with little aunt Jun Hee advising her how to go back so she can still spend more time with her Dad and Mom.

Outstanding drama, with an excellent performance by Heo Jung-Eun, the female lead actress. I can't get enough of her acting performance, her facial expressions especially her eyes. She was only 9 years old during filming, how a 9-year-old girl put up such a good acting performance baffles me. Oh Ji-Ho, Park Jin-Hee and Oh Yoon-Ah's acting performances also help to carry the show.

The drama mainly reflects the life of the FL (Geum-Bi, portrayed by Jung-Eun), who was being abandoned by her aunt after being diagnosed with the Niemann-Pick disease type C (NPC) and had to look for her dad who was serving time in jail. Eventually, the FL crosses paths with many other not-so-good and bad people, including a lonely woman who lost her youngest sister due to an accident, his dad's friend-turn-enemy, and her alcoholic biological mom -- and the drama beautifully shows how the FL changes all the people around her to be better, making us fall in love with her.

This dominates the first 12-13 episodes of the show, and then it changes when the FL's disease symptoms start to develop, and the last 2-3 episodes show how the FL fights for her life -- she is determined not to give up easily (despite Death and Mr. Fox encouraging her to go to the bright light at the end of the "forest tunnel" so that she can end all her pain). She still wants to live because she still wants to spend more time with her Dad and Mom.

Overall, this is a must-watch drama. It has a so-called "happy" ending (which is more of a compromise between sad and happy, to be honest), a good cast, and a good OST (I love the opera/orchestra-type chorus song). Highly recommended!
