Hello and welcome back. Today I would like to share an article from another blog about creating love interest characters. It is available here.
I would say I agree with the article Renee Miller wrote. There is a difference between soul mates and the love interest. The love at first sight is not something that usually endures.
And probably most important, the love interest character should not be the perfect man or woman. Like she said in the article if the person is so rich, attractive, etc. he or she would have already been snatched up by someone equally great.
Hopefully this helps, have a great day.
