you are washed up on what seems to be a beach, the world has become a real wasteland, because people got jealous of other people and bombs went off basically

i wash up, and some mysterious person grabbed you by the back of your outlandish jacket, and he drags you to some sort of base

Minutes later you wake up....

Hm? Oh, you're up... he seems to be around 19 you're lucky I saved your life...

he seems to have little to no attraction to you
