'Since when was my floor so comfortable that It felt like I was floating in water? Kim rok soo, a Korean man who fell asleep on the floor while reading a novel, wondered as he opened his eyes only to see that he wasn't in his room on the floor, but actually underwater! Nevermind being underwater! He had a mermaids tail! Wait, wasn't mermaid the female term, so a mermans tail? ------------------- Kim rok soo transmigrated into another world again only this time it is not into the book "the birth of a hero" he read. And also not as a human.
