Li Lu wanted to know when she should do certain things, and the best way was to observe Gu Xiaonuan's behavior.
However, if she acted according to Gu Xiaonuan's cues, many things would be out of Li Lu's reach.
If Li Lu ever wanted to join forces with Si Yuchen to make Gu Xiaonuan understand her feelings for him, it definitely wouldn't be in this way.
Li Lu would eventually realize that her current indecision was all for Gu Xiaonuan's happiness.
If not for Gu Xiaonuan, why would Li Lu risk upsetting Si Yuchen?
Si Yuchen is a person of unpredictable temperament; it's hard to say when he'll notice Li Lu's intentions.
Because Li Lu acted for Gu Xiaonuan, while also greatly helping Si Yuchen, he didn't show any signs of displeasure.
Otherwise, this would definitely become the biggest issue between Si Yuchen and Li Lu, making their problems even more severe.
Li Lu wasn't worried that Si Yuchen would interrupt her at this time, but there's always the chance of settling scores later.
