She had two personal bodyguards. One was Xueno, and the other was called Yu Nuo.
When she returned to her home country, both were supposed to accompany her. However, there was a minor glitch with Yu Nuo's visa, and he couldn't make it back with her.
Once Yu Nuo's visa was sorted, Ye Xinglan told her that he had assigned a task to Yu Nuo, asking him to stay in Country Y for a while longer to handle that task.
Although she couldn't understand why Ye Xinglan chose Yu Nuo when he had so many people under him, her long-standing deep-seated respect for Ye Xinglan precluded her from saying anything other than expressing her agreement.
She hadn't anticipated that Yu Nuo's task would take several months.
Furthermore, it was as if Yu Nuo had disappeared. His phone was off, and she had been unable to reach him.
She was worried about Yu Nuo. Ye Xinglan mentioned that the task he had assigned Yu Nuo was a secret mission, and as such, he was unable to maintain contact.
