First, don't be tricked by the name, there's absolutely no Yuri in this and tho the first chapter is messy it's awesome. Even more if you can identify all of the seven boys trapped in a world with no females. Does that smell like yaoi for you? If yes then God blessyour nose, cuz you're damn right.
There's a bunch of yaoi moments and they are slowly falling for each other and etc. An~d everyone in this universe is gay (obviously)
did I mention "NO GIRLS"?
