Beautiful Promises of the First Night

It is a fictitious humorous love story. Initially I thought to give the name of the book ‘If you F your wife on the first night, she will F you whole life’. But since the book is only a humorous one, I dropped that name and give the name as ‘Beautiful Promises of the First Night’ because everybody breaks all the promises those made on the first night of conjugal life. On that day everything appears to be ideal but slowly those became unrealistic and have to be abandoned one by one.
