Actually, from the very beginning till the end, Zhao Yu was most worried about Miao Ying's refusal to retrieve her dignity after being suspended from work. If she were to act spoiled before her mother, there might be a shocking change of events.
If there was any changes, Zhao Yu's hard work would have been wasted. By then, Miao Ying could naturally head into the police station to look over the entire situation, instead of entering the mountain with him.
However, luckily, with him beating around the bush during dinner that night, Miao Ying did not show any intentions of doing so. It seemed that she didn't want to ask for help from her mother anyhow.
Plus, it was only a suspension. It was considered a light punishment. If it was somebody else, he might already have lost his position.
Tsk tsk....
When he was organising things, Zhao Yu was praying in silence: Bro System, is my spring coming? Tomorrow, please give me a "Kan" hexagram okay? Hehehe...
