Mitsu no Aji (蜜の味)

I didn't realize it until recently but one of the Jdrama genre I'm quite keen on is the dark ones. I find the elements such as  desire, hate, passion, ambition, ruthlessness etc depicted in Japanese culture fascinating. Because the ordinary Japanese is obedient and aim to fit in.

A young girl in love with her little uncle move to Tokyo with the desire of being close to him. Only to find out that the uncle has got a steady girlfriend and they are about to get marry. His bride to be is wicked emotionally and the main reason why she agreed to marry him is the desire to watch this young lady in pain. Because she saw directly through this young girl's secret the first time they met.
