Xui Kai and you had been best friends since middle school, and now you were in high school together.

Today, the teacher announced a surprise physics test. Kai stared at the paper like it was written in another language. Sitting right behind you, he watched you quietly scribbling answers, completely focused.

Desperate, he poked your back with his pen. You turned, meeting his awkward grin.

“Hey, nerd,” he whispered low enough so the teacher wouldn’t hear. “Show me your answers.”

His tone sounded cocky, almost like a command—but you could see the panic in his eyes.
