It's not that he didn't want to die, he just didn't want to die. Especially alone.
And it's not like he was just going to find some random person who didn't have the means to kill him. After all, the world is ending, literally ending, and this isn't some cliche, romantic teenage novel. He was prepared to be alone for the end, and that was that.
It isn't a cliche book, either, because someone comes along and he doesn't fall in love with him or it ends with tears as bloodshed.
Witness the end of the world told through a 21 year old's eyes, through dancing, freedom, and a lot of coffee.
