While trying to evade a bastard demon hunter, Ravi was sucked into a novel and... Ahhhh... 'Even if I'm trapped inside a novel, why does it have to be a BL novel?!' He spent his days starving because he was not a MAN but a succubus. Outside, men lined up with just one look at her, but here, they were as cold as ice. Even if she dressed like a man, she was rejected and dumped as if they instinctively knew she was a woman. Like that, half a year passed. 'What if I starve to death because I can't eat regular food? Anyone is fine, so have it by me...!' She needed human vital energy to stay alive. "Hey, glasses! You know me? Why do you keep looking at me?" "It's just that- You're pretty." 'Geez, look at him!' It was the first time she heard that word after falling into this wretched world. She would spend the night with a nerdy-like guy she met at a bar thinking it was just a one-night stand but... "What are you doing standing there? I might explode if we slow down." "Huh...? That face..." 'Why are you- I can't die like this!' When she took off her glasses, she realized the man was the demon hunter chasing her. But she, Regan, didn't remember what happened outside the novel, and the evil demon didn't miss his chance. Predator and prey. Succubus and hunter. What choice would Ravi make to survive the collision of two opposing lives that could be paralleled forever? "We should do it once a day from today. Baby."
