Is this Hero for Real?

[From the author of FFF-Class Trashero:] There has never been a hero like this before! Is he a hero or an actual demon? Kang Hansoo was summoned to this world with his classmates. His classmates were amazed by this brand new world and the magic in it, but the only thing Hansoo wanted to do was quickly return home. “Why would I give up my warm, comfortable house to have an adventure in this world…? Even the goddess that summoned me said that if I wasn’t willing to, there was nothing she could do to force me and promised to return me to my original world. She did teleport me, but… When I opened my eyes, I was still in this world! All of my friends were gone, and the only thing around me was monsters!! A goddess tricked me…? How do I get back home now…? More than that, how do I survive here…?!“
