The article starts from my sister Wenwen when she was young. From her brother's perspective, she looks at her sister from her ignorance of sex, curiosity to playing sex games with her brother.

The fire of hell burns me, but I still yearn for the light of heaven.I have been adapting my real life experience. I have struggled for a long time.

I have always wanted to make myself believe that falling in love with my sister and having sex with my sister is not a sin, just like the love of a transgender person or a gay person, there is no sin. It’s just that this social norm cannot tolerate sexual behavior among relatives who are related to blood. This is our sin and forced me to make a mistake. Maybe all this has been wrong from the beginning...
