This book is titled What Makes an Archrival? It's about two equally matched rivals.
The two main characters are Bai Jinwang and Shen Yanqing.
The story is about how Bai and Shen hate each other, with a little love mixed in.
Each of them has asked himself countless times, “What makes an archrival?”
Shen Yanqing: “Would an archrival really be this stupid? What makes an archrival, anyway?”
Bai Jinwang: “How could I possibly like him? What makes an archrival, anyway?”
...The two have fought and argued since elementary school. This story is mainly about the little love mixed into their mutual hatred: from archrivals to partners, then one dies and the other follows him in death. They both die, so it's an HE! I don't understand what you mean by BE.
Theme: An archrival is an archrival. Hate is hate.
