Joo Yi-Gyeol, who sleeps 22 hours a day has Rostov Syndrome. Learning to escape from the body while asleep, he follows a golden butterfly he encountered one day and crossed to another dimension. And there, he met the 4th prince Seth and saved him multiple times… * * * “Who said you could die as you please?” Seth’s hands wrapped around Yi-Gyeol’s face. His cheeks, wrapped in those big hands, felt excessively hot. “You can’t die even if you want to.” Seth’s face came close. His and Yi-Gyeol’s foreheads lightly touched. “I am the owner of your body. You can’t die without my permission.” Yi-Gyeol could just inwardly shed tears at Seth’s mysterious remarks.
