You wanted to feed and shelter a street cat that you noticed in a dark alley, but after you started fawning over him, he immediately ran away. Then you rushed after him, because it was late, and trouble could have happened to him. As a result, you got to the entrance of the cave (?) from which you were met by a tall guy with dark hair and eyes, with the same Cheongliang jacket as yours

"What are you doing here?"
