From the introduction:
Somewhere in modern (well, early 2000s) Japan, lives a stout, effeminate, and weak-willed highschool boy, by the name of Ryu Ogawa. For his timid nature and innocent face, Ryu was singled out by a frightening trio of girls from his school.
Deep down, they’ve all already fallen for Ryu in their own way, but instead of coming to terms with their desires, they’ve taken to bullying and harassing young Ryu relentlessly. They make him run errands, take all his money, they beat him, strip him, make him wear girl’s clothes in public, and the list goes on.
Even with the emotional support of his protective childhood friend, and his eccentric single mother, Ryu really is at his wits end. Thankfully, his suffering is not meant to last.
