Getting to know someone is not so easy. Their perspective as well as feelings are to be shared. With the influence, a part of them gets changed. There is a man who inadvertently gets to live with a child. Words like ‘family’, ‘love’ or ‘parentship’ are not familiar to him at all. As they spend time together, however, he begins to learn some new feelings. He grows up to have a warm heart. This drama is the story of a family who is not blood related but shares the strongest bond ever. By watching them become one family, this year’s cold winter will be much milder.
