This was a japanese drama that I picked up without knowing much what to expect. A drama about chocolate can't be all that bad. But I have mixed feelings by the end of it. While most of the time I was taken aback with the high tolerance for immorality in this series, I do admit it was intriguing to watch for it was less straight forward than your standard romance. I don't have any particular characters to root for because the characters make all sort of choices, regardless whether it's rational or not, right or wrong, dumb or dumber, so I thought whatever endings they have is what they deserve. It's life.
I wouldn't recommend this unless you can watch it with an open mind and mature enough to differentiate between good and bad.
