Bpo Bpo was previously the pet of Miss Han, but was given by her father, Byung Han, to a reluctant Jin as a gift after Jin did not present Byung with a beating on behalf of Mr. Paik. Jin surprised his wife, Sun, with the dog as a gift and as company for her since he was working long hours for her father. Jin informed her that she would have to train it and feed it. Sun eventually grew to love the dog, and named him "Bpo Bpo" which means "a kiss".
