I’m writing a story about a biracial superhero. He’s in his 20s, and his dad is a Black billionaire. His mom is Japanese, and she comes from a wealthy family. I don’t want to give too much away, but there is something about his family’s history that resurfaces, and it connects to his powers. He is basically trying to find out what it is. My friend says the story is stupid and no one would want to read it.
OP gave some surface level details that are pretty much all existing tropes…
If someone read it and said they didn’t like it, the issue probably wasn’t any of the things OP said.
But writing is a skill, you don’t start out good at it, you get good by doing it a lot. Every author’s first stories suck
