Jin Zixuan

Jīn Zixuān (金子轩) was born as a young master of the Lanling Jin sect, was later on given the title The Citrine and eventually joined Wei Wuxian's Imperial Harem. He was the one who invited all of his father's illegitimate children (that he could find) to the Lanling Jin sect and took them in as his siblings.

Personality
Jin Zixuan appears as an arrogant and self-centered person, as one would expect from the Lanling Jin heir, but if one digs deeper, you will quickly notice that it's all just a facade to fit into his sect and also to appease his father.

He is shown to care about his siblings a lot, apparent by how readily he took all of them into his sect without consulting his father, and while he can be a bit dense and ignorant, he does have a good heart and is always striving to overcome his arrogance and become a better person.
