There are stories about the Jang Mountain Tiger, a ghost that lures its prey by imitating humans before devouring them. Thankfully, it’s just a ghost story…right? Ever since Geonpil’s roommate, Yeonseung, returned from a trip up to Jang Mountain, something has seemed off. He’s used to Yeonseung’s moods—they’ve been roommates and then some for four years—but now the other man has a hunger unlike ever before. And when that insatiable appetite goes from food to something far more physical and feral, Geonpil is still drawn to “Yeonseung,” even as the danger increases. Will he be able to keep the beast at bay, or will Yeonseung devour him whole?
