Yang Heng arranged a single room for Ye Jian not because she didn't know anyone in his class. He just felt that a lady like Ye Jian would place more importance on her privacy.
Just like him, when he lived in the dormitory in school, even if it was his classmates, he hated it when they asked him about his private matters.
Ye Jian was a year lower than them but to the young men and women in his class, this junior sister was a mysterious existence. They aren't able to control their curiosity and want to know more about her.
Hence, if Ye Jian shared a room with others, she could forget about sleeping tonight.
This thoughtful arrangement was enough to tell that Yang Heng was a considerate and thorough person even though he was a man.
The vehicle they were sitting in was the bus arranged by Yang Heng's Aunt. It could fit 56 people. Including Ye Jian, there were 55 people on the bus. Only one seat was left empty.
