JE is quietly writing her novel in the Full House, when all of a sudden her friends, Dong-wook and Hee-jin, come to see her. The 2 guests start boasting about winning a premium from a bank, and offer JE to share with them this opportunity to travel overseas for the first time in their lives. Although JE feels leery about the offer, as she believes there is no such thing as a free lunch, she agrees to join her friends.
