I was developed by my classmate!

Haruyama, a cheerful boy, is chosen to play the role of Dracula's "bitten one" in the school festival play. The role of Dracula is played by the school's cool prince, Tokiwa. During practice, Tokiwa bites Haruyama on the neck, causing him to make a "strange voice" and become the laughing stock of the class. Tokiwa says he will help with special training so that he will no longer make the "strange voice." While training alone after school, Haruyama finds himself excited by Tokiwa...!?
