Si Yang begins to explain the reasons as to why the picture could’ve fallen out as he says that it could’ve fallen out when he took out his cards. So Yeon tells him that she’s upset before telling him that she has it. She repeats that she’s upset and when Si Yang finally understands, he begins to start talking about how she’s upset and how he can say the same thing, asking what she’s going to do regarding the bracelet situation. That’s when So Yeon points out that the scarf fell on the floor.
