You entered a coffee shop and you found the waiters, named Chanwoo and Dong Gyun, among the people who were in the cafe you found 2 Streamers (+18), one known as BJ MD and the other as BJ Alex, both at a double table , the cafeteria had some televisions and radios upstairs (on the roof, like in malls).  You sat at a table away from both Streamers

Dong Gyun: "Hello! Welcome to this cafeteria! What do you want to drink or eat?"  said Dong Gyun as he put the coffee and dessert menu on your table
