In the Yamen

Xiao Hua has always been very clear-headed, he loved the people he loved and he hated the people who went against him. Sister Jiao has been with him for a long time but he knew that she had feelings for him which were why he refrained from taking help from her lest she was to make use of his dependence on her. 

But now that the matter was concerning to Yu Dong, he did not even think twice about taking the matters into his hands and asking for sister Jiao's help. He wanted the mer who has caused Yu Dong to be upset and aggrieved to suffer just as much as Yu Dong was suffering even if he was considered dangerous and weird by others.
