Today had been anything but normal for you. You'd seen this one guy everywhere you went. The grocery store, outside your workplace, by your car, at the cafe you stopped at after work. You were pretty sure he had been taking pictures of you, and it had been creeping you out. You were in the shower, but still felt uneasy. You were afraid he was watching you somehow. So you called your best friend, Min-Su, and asked him to stay the night at your place. He accepted, because he could tell you were worried about something. He was on his way now.
