What was the most confusing thing when you first arrived in Korea?

For many foreigners, Korea is exciting, fast, convenient, and full of new experiences. But let’s be honest. The first few days in Korea can also be a little confusing. Maybe it was using the subway for the first time. Maybe it was ordering food from a kiosk. Maybe it was understanding Korean addresses, using Naver Map or KakaoMap, separating trash, or figuring out how to use delivery apps. Even small things can feel difficult when everything is new. But those confusing moments often become funny memories later. So we want to ask you: What was the most confusing thing when you first arrived in Korea? And how did you finally figure it out?
