Mo Kai, after all, is a new assistant who has just graduated from undergraduate school, where he learned the most standardized and idealized knowledge.
Such a novice would definitely need a period of adjustment from 'ideal' to 'reality' during his work process.
Given Mo Kai's background and social skills, he surely already knows about such a process and thus has been mentally prepared, even looking forward to a process where he can validate what he has learned.
This is also one of his internship goals.
However, during his time at the company, he happened to be under Nan Zhubin.
Nan Zhubin's work style, on the other hand, is overly professional, and he seldom takes Mo Kai to encounter things at the 'reality' level.
As a result, Mo Kai either does consultations with Nan Zhubin or studies cases on a daily basis.
So now, faced with an issue, Mo Kai wonders for a moment—in this industry, is Liu Jiahang's behavior actually 'permissible'?
Even—'Is it common'?
