According to the Romance Writers of America, there are two things every good romance needs:
A Central Love Story: The main plot centers around individuals falling in love and struggling to make the relationship work. A writer can include as many subplots as he/she wants as long as the love story is the main focus of the novel.
An Emotionally Satisfying and Optimistic Ending: In a romance, the lovers who risk and struggle for each other and their relationship are rewarded with emotional justice and unconditional love.
