Hello everyone, I'm Xiaoxue~ Today, I'm excited to introduce a legendary work that originally started as a series of CG images, and has since expanded into a novel, an AV adaptation, a game, an H anime, and even a manga. The story I'm referring to is the infamous 『Sakusei Byoutou ~Sexually Awful Nurses Managing Ejaculation Life at the Hospital~』 (Chinese: Hospital Anecdote ~A Hospital with Only Malicious Nurses~).

Original Story
The original 'Sakusei Byoutou' was released as a CG work by the Ejaculation Research Institute on DLsite and FANZA. The story details a weak protagonist, Yamada, who suffers from a peculiar ailment where he experiences intense testicular pain if he doesn't ejaculate every three hours. After an accident that results in a broken arm, Yamada is hospitalized and unable to relieve himself. He must rely on the hospital's nurses, who are notoriously horrible, to help him, leading to physical and emotional torment for the timid Yamada...

The original series consists of 11 episodes, during which Yamada meets more nurses and begins to understand the harsh working conditions of the hospital. However, due to past bullying, their relationship remains strained.
Later, Yamada's attending doctor discovers that Yamada’s condition could aid their pharmaceutical research. In reality, the doctor, along with the head nurse, is engaged in illegal drug trade for profit. An investigating prosecutor also comes into contact with Yamada, placing him at the center of a conflict between two powerful forces. Ultimately, Yamada decides to assist the police in uncovering the criminal organization within the hospital.
Reasons for Popularity
So, why did this CG-style work become so immensely popular? After watching it myself, I believe there are several reasons.
It caters to masochists. From the first episode, Nurse Tachibana's disdainful glares and contemptuous attitude, combined with the necessity of assisting Yamada with his physical needs, strikes a chord with many masochists. Moreover, Yamada, being a very relatable weak character, harbors admiration for Nurse Tachibana yet is treated like trash, making it an ideal match for the masochistic viewer.

The later parts of the story are intriguing. The first few episodes primarily focus on introducing nurses with different personalities, but once the main storyline unfolds, it becomes highly engaging and leaves you curious about the outcome.
The derivative works, such as novels, games, H-anime, and manga remakes, are all of high quality. They enhance the original nurses' insane allure through more exquisite illustrations.

Just how popular is this series? Despite the decidedly adult-oriented nature of its name and content, it has even branched out into a non-adult-oriented manga that is being serialized. Although it was initially announced on April Fool's Day, it seems to be taken seriously and is still ongoing. The world is indeed a fascinating place~
