I liked the basic idea of the series. There are the main characters: Cha-Yeoung and Lee Kang who once briefly knew each other and later on they meet again. The story evolves around a misunderstanding because of which Lee Kang pretty much hates Cha-Yeoung, the woman, who in his concept or part of the story betrayed and left his best friend. So for him she is a devious, heartless person and the story is how these negative feelings turn to admiration and love with time towards her.
The following things I didn't like in the series:
-I don't know why the series is called: chocolate, when almost no one ate chocolate in it. About 4 - 5 times they show some chocolate, e.g. Cha-Yeoung walks into a shop and looks amazed, bright-eyed on the chocolate creations but she eats only once during the whole series. I think Cooking & Eating would have been a better title. They didn't even try the snowball size chocolate shashimi or whatever it was called, which was made by the little Kang.
- I also hated this 'I love you, I need you' song. It was played in the beginning very often, then thankfully the Korean version or part of the song was audible which was a huge relief, it was that sirupy.
- Cha-Yeoung is pretty much a young Mother Teresa. She is way too selfless and kind. She is almost like an angel. An example: an upset grandmother is sure that her grandchild got ill because of Cha-Yeoung's cooking, so she starts to beat her up. And what is her reaction to that? Nothing. Nothing at all. She just stands there and takes the beating until Kang appears (when she is already lying on the floor) and stops the aggressive grandma. A similar situation: her brother quarrels with an old man who loses his temper and starts to beat him with his stick. She jumps between them and gets beaten until Kang appears again and helps her. Or another one: Kang is exhausted and lies down on the floor, without a blanket or a pillow. She enters the room, opens a cupboard that has a pile of pillows and blankets and she puts a pillow under his head and covers him with a blanket. And what does she do? She also lies down next to him, but she doesn't take any pillow or blanket. So, for me her character was too good to be true.
