Im sorry but this isnt what im looking for.. thank you though :)
Its not a yaoi manga, but i cant remember it.. im pretty sure its a fantasy, like the guy had crush for his classmate, and then hisclassroom had some sudden movement, and the entire classroom moved to another dimension as a game players the stats all 10avaragely and this guy job was a Crafter or something like that. He tried to save his crush from something dungeon like and he trapped inside there and to survive he ate monsters and turned out he could absorb the monster power. I think he met a vampire at the last update... thats all i could remember
