This drama got me. That's a clear - MUST WATCH
I'm starting being afraid of the ending of this masterpiece. Because actually in the real-past history she died 33 years old in the 10. month of her third pregnancy with her unborn child in the womb from liver cancer and he was so deeply sad touched that this romantic relationship (his ever only beloved woman) become sad history afterwards by his actions in grieve.

Sometimes you really ask yourself, how can live be so cruel. He lost his father due to being executed by his grandfather, he later lost the only woman he ever loved due to liver cancer and he lost his son with her, the young crown prince by sickness at age of 4 and even his unborn child with this woman, whom died in its mothers womb together with her.
