Lee Jang Woo's fatherly love was revealed.

On the 15th episode of 'I do I do' that aired on July 18th, Park Tae Kang(Lee Jang Woo) read a story book for his daughter Ankle who is still inside Hwang Ji An's(Kim Sun Ah) stomach.

Park Tae Kang who is preparing for his study abroad in the states went to the hospital to ask Jo Eun Sung(Park Kun Hyung) for advice.

Park Tae Kang told him "If this continues, ankle will become more accustomed to your voice and forget mines..."

Park Tae Kang even after returning home showed his fatherly love by kissing the ultra sound picture of his daughter.

To let his daughter listen to his voice whenever he is away, he recorded a story book in his voice for her.

The story book's title was different to begin with. It was called 'Fairy Shoemaker' as Hwang Ji An wants to raise Ankle as a shoe designer.

Park Tae Kang recorded the story stating things such as "The shoe maker didn't do anything wrong but he just continued to get poor" in a very soft and sweet voice.
