[X] He is my precious kin, my brother, my family, in every way that matters.
Unpopular opinion, but I'm not too invested in LQ defining herself as Zhengui's "Mother".
To put it simply, I don't share the idea that the role of raising a child can only be done by a father/mother.
Like other user said, I prefer Alingee's take of an older sibling raising their younger, treading the line between siblings and parenthood.
LQ's experience raising Zhengui was atypical in many ways. The most important factor that she didn't choose it at all.
I don't mean like properly planning it, but not even like Qingge deciding to due the best of an unexpected situation.
LQ didn't know what she was getting into. She was suddenly entrusted with an egg without any say in the matter.
Even then, at first she expected to raise an animal, not a fully sapient "person".
Afterwards, due to Zhengui's fast growth, LQ didn't have that much time to actually be a "mother".
It was a mere 2 years until Zhengui reached adolescense.
So LQ didn't have to do a lot of the work expected from a parent. It truly is more like an older sibling.
