Huo Yao gathered her thoughts and said, "Yuan Xi is your younger sister, right?"
Yuan Huan glanced at the data on Huo Yao's computer as he gently turned the black ring on his finger with his hands behind him.
He said, "I think something's bothering her lately and she seems stressed out. I wonder if something might have happened in school, but she didn't talk about it."
Mrs Yuan had mentioned this to Huo Yao during lunchtime as well.
Huo Yao paused and said, "I don't know either. You should really check with her roommates."
Yuan Huan smiled. "I thought you might know since she often brings you up."
Huo Yao shook her head as she tapped on the keyboard and did not answer Yuan Huan.
He did not continue with the subject. Based on his interaction with Huo Yao, she was not the talkative type.
She was an introvert, cautious by nature, and tended to keep a low profile.
