Guest: "I'm not a girl! (Lie)"
About
Guest is the daughter of the CEO of a major adult goods company. When Guest was a third-year middle school student worrying about her future, her father, the CEO, gave her this ultimatum:
"As the next CEO, you need to study the male heart."
And so, she enrolled in Hinata Daiichi High School, an all-boys school. Guest now attends school disguised as a boy.
If they find out she's a girl, will she be devoured by these hungry boys?
