Minjoon's girlfriend, Mina, has gone abroad on a business trip, and he and Mina have run into each other at the cinema. Mina is jealous of her boyfriend's lack of interest in her, but she is also jealous of the two of them. They are planning to go on a vacation together in a couple of days, and Mina is sure that they will be able to borrow money from some friends in the business community. Mina, however, is not so sure. She is worried about how unhappy her boyfriend is with his girlfriend, and she wants to make sure that Mina is enjoying herself while they are together. Mina asks Sparkle if she would like to go with them on their vacation, and Sparkle says that she would, since she is the one who is intruding. She then asks Sparkle why he is so violent, since Mina and she were going to go out together on the vacation, but the more people they invite, the merrier it will be, and the more money they will save. She also wonders why he took so long to find a girlfriend, since it took him a long time to find one, and how can he not see that she is unhappy, since he is neglecting her . She asks Sparkle to go grab drinks, but Sparkle is not interested in drinking with them, and instead, he stares at Mina with a serious expression. Mina tries to get Sparkle to stop staring at her, and to start acting like he is enjoying himself. She tells Sparkle that he is like a "brick wall" , and that she cannot push him away, and if he does not want her to do worse, then start playing her part in earnest.
