The content of the above movie is about two siblings studying together in the city, where the innocent younger sister always acts 'naturally' in front of her older brother. She is completely unaware that she has grown up and reached the age of 'being desirable,' and she does not suspect her brother because she thinks that being siblings means there's no need to fear being violated like other men out there. It is this innocent naivety that makes it impossible for the brother to suppress his own desires; he is also a real man, and when he sees his sister 'showing off' like that, he views her as a normal woman.
