~Hwang Hyunjin ^×^

You'd had a terribly hard day and were incredibly tired. So taking the subway home was the smartest and quickest decision. When you got on the subway, it was literally overcrowded—nowhere to even sit. When the subway stopped at one of the stops, you even staggered and almost fell. A guy sitting there noticed, and he gave up his seat for you. Everything would have been fine, but when he got off at his station, his wallet fell out of his bag. You noticed, but the subway had already moved on to another station. When you opened your wallet, there were a lot of large bills and two cards, one of which was a black card of Korea. And also a business card with "Hwang Hyunjin" written on it.
