――My name is Yamada.
I'm your average student who was hospitalized because of broken arms. However, I'm also suffering from a rare disease which causes "severe pain in my testicles if I don't ejaculate every three hours".
There is a rumor that the hospital where I'm admitted only has "nurses with the worst personalities". This is more than just a rumor, it is a fact... As I have seen with my own eyes, such a terrifying reality.
