For Xu Chang'an, if someone can come to mind when facing difficulties, it means they have a very good relationship.
For example, the teacher, Zhu Pingniang, the Hall Master of Steward Hall, Timekeeper, or Senior Wen.
This is his trust.
But there are also more extreme situations, such as absolutely not wanting her to know he's having difficulties... the relationship is good to the extreme.
For example, Miss Yun.
Of course, discussing Yun Qian alongside others is somewhat of a dimensional reduction attack.
Xu Chang'an knows his reputation as the only male disciple of Muyu Peak in Chaoyun Sect, like how people say his appearance was nurtured by the women of Muyu Peak, such topics have long become stale.
Now, especially during times of welcoming guests from all directions, many are interested in this man who, in less than two years, has 'conquered' Muyu Peak. They say all sorts of things about him.
