After he arrived in Macau, him and his dance team checked in at a hotel. One of the fans was waiting outside the hotel and afterwards they came down to go eat. While they were eating, the fan went to buy them some portuguese tarts (famous local speciality of Macau) and gave it to him when they came out from the restaurant. He thanked her. She said to him, this is really famous from Macau, there is even a shop selling this in Korea. She was about to tell him that it was called a portuguese tart but before she even said the name, he beat her to it and told her that he knew what it was called.
