As an Author, He Is Given the Task of Conquering the Male Protagonist.

As a current person, I am always surrounded by all kinds of girls, but in an incredible Shura field, I actually traveled through time and became... A passerby girl in my own novel? And I got the task of conquering the male protagonist and playing the single-line Happy End. Only after completing the task can I return to the original world. What should I do?
