I do belive that in chapter 211 it gave us a hint that the professor is coming to Korea. We can see that one of the dialogue says "I heard he has a stop in korea on this tour". Seeing the recent wip on Twitter we see kathy and the professor at what looks the airport. So I'm thinking that maybe the professor is going to perform in Korea and that Kathy might actually be the one to run into garam first at the coffe shop.
Alright I have a theory
