Li Lu's mood, Gu Xiaonuan's mood, in short, they are both doing this for each other's sake.
No matter what decision Gu Xiaonuan makes, or what approach Li Lu takes, it's all for their own good.
Li Lu is genuinely risking her life; otherwise, how could she face Gu Xiaonuan without a care?
Li Lu knows that Gu Xiaonuan can get angry. The reason she hasn't gotten angry yet is because Gu Xiaonuan understands that everything is done for her own good.
Who knows when she might overstep, exceeding Gu Xiaonuan's limits of tolerance? Would her best friend really become angry with her? If she does get angry, what should she do then?
Li Lu also struggles to understand what is truly in Gu Xiaonuan's heart. If she could, she wouldn't still be unclear about what to do now.
Solving a problem is easier said than done. Especially when it involves resolving Gu Xiaonuan's inner issues, her emotional knot.
