I'm just gonna leave this here. I know, it's complicated and I'd like to explain but it would take long... so I'm doing it anyway bc I've put so much thought into this and this family exists for quite some time. This helps me in case I decide to write a fanfic someday.
Also, like I've said, this is just an updated version, the original can be found here.
I'm sorry if I f*ked up the Chinese names.
So let's start. I'm going to paste what I've said in my original post with some additions and corrections (especially grammatical ones):
First, trigger warning!
We have Fei and Jun who are both from very respected families. They were part of an arranged wedding and, surprisingly they liked each other. They proceed to have their first son, Wei. Because he is the oldest, he was expected to be strong, a great leader, and the next head of the house. So he learned everything from how to fight to a second language and high-class mares. The second one who was born later was Shen. He was cheerful and liked freedom. He respected his brother and parents but he didn't really enjoy the strict environment, so he left the house at the age of 20 to travel around the world...
And from here he meets Catherine who was the heir of the queen (the person who rules among all the magical creatures and is responsible for maintaining peace between them and humans). At a first glance, she seem really kind and also a free spirit but was actually very, very crazy. She often had mental crises and started destroying stuff around the house. She was even accused of killing her mom and treating her partner (Shen) poorly. She and Shen had 3 kids, 2 of them made their own families while the youngest one stayed single until this day. She died while giving birth to the youngest child because of "complications" (in actuality this death was planned but made seem like an accident).
Angela (Catherine and Shen's middle child) was living with her father and her two brothers and aspired to be part of the royal guard but the new queen didn't like her too much. So her majesty sent her on a trap mission (basically expecting her to die) where she met Damon. He seem really nasty at the beginning but gradually fell for her, her kindness and beauty and stuff happened. They had 3 kids who were and still are hated by some members of the family (their uncles especially) because their father is "The Devil" and a man hoe. But the parents got separated because of some legal issues and so do the children. They meet again when they were adults. Shen was killed in a battle by none other than Damon (these two hate each other guts). Angela died a couple of years later from poison. She did become the queen, but for a short period of time.
Alice (the oldest child of Angela and Damon) moved from home a year before her grandfather died. There, she meet a guy who she dated a couple of years then meet Ren, who she married later and now has 2 kids.
Alan (youngest child of Angela and Damon) starts dating Rose (not present in the family tree), marries her, and decides to adopt a child because his wife can't have kids.
Hélène (middle child of Angela and Damon)... well, she doesn't have kids yet because things got complicated in Eldarya.
Adam (Angela's older brother) starts dating Minerva and they have a daughter, Christina. She didn't appreciate their hatred towards her cousins so, when she became an adult, moved alone where she fell for a doctor, who was a good friend of her grandfather, Tao, also known as Daniel. They have a daughter, Isabella. After 20 years of living together, they broke up because of some misunderstandings.
On the other side, the other Wang son, Wei, married Huan and they had a daughter. She died a couple of years after from an illness. Wei also died at the same time as his brother, with this keeping their promise that they'll die together.
Ai (Wei and Huan's daughter) meets this guy, "Stephen Rose", who is actually the devil (the real one this time). They had a daughter in a really forced way and Ai decides to keep her at her father's insistence but doesn't like her much because of what happened. Ai decides to commit suicide because she couldn't bear it anymore.
After her grandfather's death, Mei (Ai and Stephen's daughter) also commits suicide, and with that ending this side of the family's legacy.
