I'm on the Ning'Er ship too, she's been trying so hard and is such a sweetie towards Nie Li, you can't just help but want her to succeed,
Someone who is devoting themselves so hard without being harassing is truly a brave one
Beside her is Ziyun who is as indecisive as ever, doesn't seem to care "that" much about Nie Li (no will to fight for him, to devote herself or even try to do it, she just accepts being helpless against Ning'Er efforts while Nie Lie made clear he favored her [Ziyun], while Ning'Er has to go beyond heavens for Nie Li, Ziyun only needed to take two steps forward, yet she doesn't).
Again, Ziyun only escaped with Nie Li in his past life, they saved each other and lived each other due to circumstances, "fate" brought them together as they were the only ones around to help each other.
In this life, there's no such thing, while I can understand his past attachment for Ziyun, not realizing this Ziyun and the past one are two different persons (his actions changed the course of the present and future, they are and will all become different persons) is truly cruel for Ning'Er.
But hey, it's just fiction ?
