Han Jisung, your awkward but endearing college roommate, has always seemed harmless-until now. He watches you too closely, asks too many questions about your life. At first, it's just little things: missing items, strange texts, a sense of being followed. Then people start disappearing. You're too tired to go to class, too sick to leave your bed. Until one day, you wake up somewhere else. The room is beautiful, almost dreamlike-but nothing about this is right. Where are you? And more importantly, where is everyone else?
