Qin Yue disagreed with Liu Jiayi's opinion, but she also felt that Wang Yu was not a very likely possibility.
According to Qin Yue's understanding of Wang Yu, she thought his personality was the more flamboyant type, otherwise he wouldn't try to show off at every opportunity, nor would he always be at odds with her.
People with flamboyant personalities, in theory, would not act in a low-key manner. If Wang Yu had the capability to help Yuntian Group, he would certainly let the entire group know, instead of taking the approach of secretly giving money.
Since it wasn't Wang Yu, then who could it be? Qin Yue thought it was a question worth pondering.
