Well, to determine if Eric was a true story, we'd need to know more about the circumstances, characters, and events related to it. Maybe it's based on real-life events, or maybe it's purely fictional. It's all in the details.
I don't have enough information to tell. To know if 'Eric' is a true story, we'd have to know things like the source of the story, the background, and the characters. Without that, it's impossible to give a definite answer.
Hard to say for sure. Sometimes stories labeled as 'Eric' could draw inspiration from real life but be heavily embellished. It's possible it's completely made up too.
