When Heaven left the set on the first day, Paula thought her life would go back to normal. Even though it was annoying she had to wait for hours and even got her scenes canceled, she let it slide. It only happened once, after all. Therefore, she thought that was okay.
However, she thought wrong.
Even though Heaven wasn't needed in the set, her effect ran deep into the production. The impact Heaven left from her first scene with Leo set the bar, and thus, the pressure and expectation from Paula were unfathomable. Heaven and Leo's chemistry impacted Paula's chemistry with her leading man.
Everyone in the production couldn't say it in front of her, but they weren't discreet in their gossip. Paula had to stay in the set, listening to everyone comparing her and Heaven. Even Director Guan was very dissatisfied with her scenes with Leo, which had built quite a tension in the entire production.
