Legendary Witches (2014)

Original title: 전설의 마녀

The four women bond and become friends, particularly when they join the baking classes being taught by Nam Woo-suk, a hotel chef. Woo-suk is a widower who is raising his daughter alone after the death of his wife six years ago. At his father-in-law's suggestion, he became a volunteer at the local prison's vocational training center, where he meets Soo-in and begins to fall for her.
