The story is great structured and consistent.

We gradually discover the story of this single mother who raises her sick son with so much difficulty.
Over the course of medical consultations, she meets again her ex-boyfriend, who has become a cardiac surgeon, dumped 7 years earlier. This complex character Dr. Nie is beautifully played by Wallace Chung.

We must also emphasize the talent of all the actors in this series. All are emotionnaly convincing ! They embody superbly, without excess or useless chatter, characters whose past, traumas and goals we discover little by little.

The actor who plays the young PingPing is also extraordinary in accuracy and sensitivity. I can only assume that if he continues down this path, he will have a great career.

The execution is excellent. Some scenes, especially the painful scenes, last a long time. We could consider that these are lengthy, but this timing is undoubtedly necessary so that the spectator understands the state of mind of the characters and their evolution. The puzzle pieces are put into place with precision and the clues guide the viewer to legitimate conclusions with context.

I have a more mixed assessment on the OSTs (sometimes jazz, but a lot of classical pieces) whose atmosphere does not always match the emotions conveyed.

In conclusion, this is not a feel-good or entertaining series.
But it is a high quality drama that will remain in your memories for a long time.
