so basically theyre from the publicity department in ch24 they tricked jiaojiao signing a contract
then in ch 29 reveals what scheme theyre doing.
basically jiaojiao signed to order very expensive film equipment, which were damage and on the contract they had to payback something like a million yuan.
because of this the external affair department (dept where jiaojiao is in) had to stop their work and hand it over to the publicity dept (the blonde is the president for that dept)
the blonde wants to take the glory and effort jiaojiao’s dept put in and also kick jiaojiao out because he’s a conniving jealous little shit (excuse my language lol)
in this chap theyre celebrating their scheme worked, but hua li (the goat) was eavesdropping and recording them for evidence since jiaojiao was on the verge on expulsion
hope that helpsヾ(❀╹◡╹)ノ~

I'm sorry, but who are those other people?
