Before you even begin writing your novel, you need to know who your characters will be. Minimally, you would want two major characters, the hero and the heroine. They will interact mostly with each other through the novel. How they interact with each other will determine the outcome of the story. Will they resist each other in the beginning of the story and by the end, fall in love? Or will they fall in love in the beginning of the story and then be driven apart by conflict? Once you've chosen them, then you need to decide what age they are, their personality traits, and their names.
Age-appropriate actions are paramount to development of the character. If the heroine is in her teens, she will react differently to situations than if she is in her late twenties. The same goes with the hero. In a romance novel, the typical heroine is in her early twenties, while the hero is older. If he is in his twenties, he should not be shown as a tycoon, without of course, he inherited the wealth. If he is in his thirties, he should not be shown doing activities that are immature for his age.
A character in your novel needs to have distinct personality traits that make them unique. By separating them from the other persons in the novel, you can create all kinds of situations based on those practices. Personality traits are typically revealed in the story through actions, dialogue with other people in the story, and sometimes through flashbacks that may reveal how that person became the way they are.
If you are not familiar with personality traits, you can begin by studying the psychology books that describe them. Some examples of personality traits are introvert / extrovert, obsessive-compulsive, Type "A" / Type "B" personalities, etc. For example, an introverted person would appear shy, does not speak much, and shuns being in social situations, whereas an extroverted person would be gregarious, out-going, and usually a partygoer.
There are many types of personalities that you can choose from for your heroine, but typically, a "romantic" female would include the following: kind, young, nurturing, loving, warm, single, sensual, does not fool around, and attractive . For your hero, the characteristics could have even more, and usually include being: older, decisive, powerful, kind, caring, single, gentle, and handsome.
Typically, you should have well-rounded characters. However, beware of making them too perfect. Readers prefer reading about realistic people, and yet at the same time, want to escape a little. Leave some room for improvement to allow character development to take place. As a writer, you will have to do some mental gymnastics to allow this to happen. Maybe she is stubborn and headstrong, and does not listen to other people's advice. Maybe he does not trust anyone, so he is wary and cautious. That's fine. Once you decide on the habits of each character, then the next step would be to envision how they would react to certain situations. For example, an impulsive person would probably react differently than a cautious person to the same situation. Be prepared to get into the shoes of your character and feel what they would feel. When a hero and heroine get together, they may help each other overcome their character flaws by the end of the story. Through their love for each other, they help each other grow as human beings, and at the same time, accept each other's flaws and imperfections. Of course, there will be some type of conflict in attaining their love. What story exists without conflict? But by the end of the story, they realize the importance of each other in their life and can not live without the other, no matter what the price. Ahhh, true love!
Once you have the age and personality trait of each character, then you need to give them a name that fits them. If the male character is a warrior or has a tough-minded personality, you would not want to give him a name that sounds feminine, like Jean or Francis. Also, be sensitive to the setting, locale, and the time period, when deciding upon names. In addition, the names of your other characters should not overpower the hero / heroine's names.
Once you have your main characters, then think about something else will be in the novel. What role will these other players maintain to help the hero or heroine go forth? If you just add someone in the novel because you like him or her, but they do not help the story, then rethink on how they could be useful to the story. Maybe they know something that might be useful to the hero or heroine, then add that into the story.
Cardboard characters are a result of focusing on one dimension of a character. The cardboard character can be either totally evil, good, funny, sad, etc. They do not waver much from that description. Sometimes they are added in the novel to prove someone's character. For example, an evil cardboard character makes the hero look good by battling with him. That's the only purpose the evil character has, to show the hero's good side. We do not try to develop the evil person's character so that he / she is less evil. However, in recent literature, one sees more sympathetic looking evil people doing their bad deeds, yet somehow managing to make the reader feel sorry about them. Those complex types are not considered cardboard characters.
No matter how well you think you are writing, always go back and double check your work for consistency. Make sure that if your hero has blue eyes in the beginning of the story, that he still has blue eyes by the end of the story, etc. Also, make sure you know your characters before you write. If you do not, it will show up in your writing. Through the story, you have to carefully describe the real person in all their glory, as well as their character flaws. When I went back and read the first draft of my romance novel "Lipsi's Daughter, I found that I tended to lean more towards making my characters too good. conflict. Conflict drives the story forward.
The final balancing act will come at the end, where you will have created, or synthesized a whole new person that has evolved into a better human being from the lessons that they learned in the story. So now that you've read this section, go ahead, write your characters. Make them come alive!
