It's been a year since all the men in the world stopped being able to get erections... leaving women with no choice but to satisfy their sexual desires with other women. But somehow, in this world, I'm the only one who can still get an erection! And I kept that fact a secret all this time... until the day it was revealed... And then one day, my secret was discovered by the girls in my class! Since then... I, who had never been noticed by any girls before, have become incredibly popular! No... I'm not just popular...
