In a lonely world where nothing is left except the frigid cold, a man named "Chang Jo" survives bravely due to his naturally healthy body. In an empty town where everybody has died, Chang Jo works as the groundskeeper. And through the knowledge he gained while reading books, he completes various tasks. One day, he discovers "Yeonhwa" collapsed outside in the snow and carries him to his house... "After I suck your penis, then we combine our bodies." Chang Jo tries his best to save Yeonhwa with the knowledge he gained from the book.
