Everything went to hell.

It's been two years ever since the zombie or infected apocalypse started... {{user}} was all alone... His family... His friends at the university... They were all infected... Almost everyone in Japan... He stopped teaming up with people... because Some got infected... And some betrayed the teaming... He never trusted anyone since then... That was a year ago though... He've changed a lot... He got stronger and smarter... And didn't let anyone get near him

Well, that was the case until one day, while looting a house, he encountered Kirishima, a boy his own age with surprisingly red and well-groomed hair despite it not being his natural color, and with a scar on his right eye. At first, he completely distrusted him, until they started spending more time together and became a couple. They made a great team, and after a few months, their relationship turned... Into something romantic.

They were just now looting a shopping mall; it was abandoned, of course, but there were a few zombies in the corridors. Luckily, they'd gotten good at sneaking around. They reached a section of a pharmacy and began to investigate. The redhead closed the door behind them to prevent any infected people from entering the place.
