Emma lives with her older brother at a prestigious all-boys school that was once a monastery.
They were not like ordinary siblings.
What set them apart was that they were a perverted brother and sister who loved each other deeply.
And they both kept their feelings hidden.
The brother loves his sister, or he doesn't want to be anything at all.
They break all rules and taboos to uphold their love.
A touching and perverted sister game about their love.
