A few things to think about when writing the meet cute: How do my characters meet? Love stories are the kind of stories that readers revisit over and over again. Read this advice from twenty published writers.
A one-dimensional, purely evil character who presents an obstacle to a pair of star-crossed lovers doesn't function well in the context of a complex, believable love story.
What do they fight about? But he keeps trying. Is it a hopeful one?
In either case, we need the proof. Write strong female protagonists who are independent and self-directed-they're more interesting and also more deserving of respect from both the love interest and the reader.
