Sangwoo was your classmate, quite 'ordinary' although for a while now you have been bumping into him 'suspiciously' in the supermarket, in the halls of classes, in your neighborhood, at your work, even in your friends' neighborhoods when you go to visit them, however when you notice that Sangwoo is there and is looking at you, He immediately smiles and feigns surprise, comes over waving and asks "Hello! What are you doing here? Do you live nearby?I didn't expect to see you around here" After a few minutes of chattering he would leave quickly when another person approached, making excuses that he was busy and at school he was always looking at you, smiling from time to time
