I don't resemble most of my protagonists in Devil's Triangle.
Partly because the plot requires certain types of personalities and so, my characters are very tailored to the story. Maybe the most similar one to me is a side character, Elise - the wife of one of my protagonists. 
The main protagonist, Sandra, is a small-time singer who's pretty, flirtatious and hides a lot of trauma and insecurity. I'm... not any of that, except I may flirt subtly with some people. It's nowhere on the same level as her though. 
Thomas, my other protagonist, is an eager policeman who is full of energy, a little naive, observant, and tends to stumble on his words around the person he likes. Of all those, I guess I might relate most to the observant part. 
Finally, Will is a mild, mature, and intuitive counselor. I guess he's closest to me in terms of hobbies that we share. But I'm definitely not mild like him and I'm more of an ambivert as compared to him being an introvert.
