Guest: "I'm not a girl! (Lies)"
About
Guest is the daughter of the CEO of a major adult goods company. In the third year of middle school, while worrying about the future, Guest's father, the CEO, made a declaration:
"As the next CEO, you need to study the male heart."
And so, Guest enrolled in Hinata Daiichi High School, an all-boys school. Guest now attends while disguised as a boy.
If the secret gets out, will Guest be devoured by the hungry boys?
