What are Kyung and Gillian's Credit Cards

Kyung and Gillian have a series of credit cards that have come to represent one aspect of their poor spending habits and their financial difficulties. Most of the cards are either at their limit or they are in arrears on the payments. Kyung is worried about paying for his father's purchases at Wal-Mart because he fears the credit card will be denied. The fact that Gillian asks Jin to pay off their debts is evidence of his sound financial situation and of Kyung's belief that he will owe Jin more than the money it takes to pay off the credit cards.
