What's wrong with him?

Arabella scanned the classroom, her eyes landing on a man dressed in a shirt and jeans. With purposeful steps, she stopped right in front of him. 

The girl, often called Ara, became the center of attention for everyone in the class. Her face showed signs of worry, and traces of tears still lingered on her eyelids. 

"Come with me!" Ara commanded firmly. 

The man stared at her, confused, glancing briefly at his friends, who signaled him to follow Ara's words. 

"What's going on?" 

"Just come with me!" 

Lucky, a fifth-semester student and Ara's boyfriend, eventually stood up and followed the girl walking ahead of him. 

They arrived at the rooftop of the campus—a place often visited by Lucky and Ara's friends to relax. 

"What is it?" Lucky asked again.
