Grandparents - give MC a warm welcome. Let her live with them when she is disappointed with her parents. Never liked An Meiyun. Came from the wealthy An family who were mostly intellectuals. They gave most of their wealth to the government, saving them from trouble when China's policies changed. Die at an old age pwrtially thanks to MC's medicine. Grandmother who was also from a wealthy family leaves MC her dowry. Grandmother leaves a few years after grandfather.

Zhou Nan - mother of MC. She's from the country who married into the wealthy An family. Has given birth to 4 sons and 1 daughter. Works hard to do her best for her family and take care of their children. She can't let go of fake daughter An Meiyun when she finds out her daughter has been switched. Repeated preferential treatment of fake daughter at the start disappoints MC, so she never gets a close bond with MC. She does try though. Dies a few years before her husband at old age.

An Jingzhi - father of MC. Looked down on his wife when he married her, because she came from a poor rural family. Lets her do all the housework. Is head of a highschool. Also gave preferential treatment to fake daughter, disappointing MC, so also never has a close bond with her. Dies at old age in hospital.

An Zhiren - 2nd brother of MC. Teacher. Is quite cold towards MC at the start. This is partially caused by An Meiyun's misbehaviour when growing up. Gets tricked into marrying one of his students. Really hates her for that and doesn't touch her. He destroys her family and manages to divorce her a few years later, after her repeated threats to commit su*cide. His ex-wife conspires to steal one of MC's sons when she gives birth to a triplet later on. Ends up in prison for life. Later marries a girl from the country and has a happy marriage with her.

Pei Jiangguo - son of Pei Yong. Was married to MC in her first life. Gets married to Guo Momo, but disappoints her in their marriage. His mother disapproves of her. His sister pushes Guo Momo down when she is 8 months pregnant, resulting in her giving birth prematurely to Pei An and him being mute and sickly when born. Divorces her a few years later and then marries Lu Keqin on instigation of his mother. This marriage becomes a huge failure from the start. Divorces her and falls for Gao Qingchen, the sister who treated MC badly when growing up. Then marries Liu Chunhua, the ex-wife of Gao Duo. He is a huge disappointment to his father and the rest of the Pei family. He is easily swayed by others. Has a low self esteem becaue his mother always put him down.

Pei Shuanshuan - daugher of Pei Yong. Takes after her mother. Is in love with An Zhixian who never likes her. Dislikes MC. In her 30s she starts an affair with a painter who looks like An Zhixian. He sells a nude painting of her at an auction which MC buys. This causes a huge scandal, dishonoring the name of everyone in the Pei family. Because of this MC's daughter leaves university and starts studying abroad. Is sent away. Later marries someone and divorces again.

I mean MC has seen the development from the 70s to 2070s and has a living space with an inter dimensional trader but those advantages kinda stop being used around the middle of the story which is a shame as the discussions with the other traders were pretty interesting and we could have had a lot more interaction with them or the impact of their situation on MC:

Also on the antagonist:

In the case of the girl with an evil system -tho not a friend- who spent more than half her life a puppet, and true, the life she gained was exactly the product of that evil system, but that sort of life, where she was considered a genius and very much hated by many, all of a sudden losing all of her ability and losing the fondness the system installed in people, how can she ask for lessons and help? Not because of loss of face, but because at her level, to become a layman overnight, it would not be possible to actually continue on. To return home, that too would've been a nightmare, no matter how much guilt she felt, she naturally would not want to be forced into a bad marriage, the same as any other person. The only thing she could've done is get with a soldier in the base, but how many people are able to give up on the dream that had been in the palm of their hands for a long time already? And the little wife who married the husband of MC's first life, to be so disdained because she made the choice to consider the future more than the present, in a house in which her husband and in laws are trying to torture her and harm her young son, and her only choice was stay and wait to be driven mad and maybe even have something terrible happen to your child again, or go abroad to finish your schooling and come back capable of taking care of him and being untouchable by both in laws and your abusive family. The fact that she left a letter and money, instead of asking in person, shows that she was aware that MC was not really ever sincere in their relationship, she had no confidence that she would accept to care for her son, and if she was outright rejected she could only stay and rot. All the while, MC actually was taking care of a child left behind by her business partner -this kid might as well be a ghost cause never mentioned when the daughter has issues later on- and not to mention the boy is almost always with MC or her kids anyway, her getting angry about the way the kid was left behind was normal, but if you actually consider the person who did that a friend, and you know their situation, while your own does give you the capability of taking care of the kid, would you not ask yourself if their actions were influenced by you. She did at first tell MC that given the situation, going abroad would be hard, but people change their minds, it doesn't mean they lied at the moment you first spoke, just that later on, they thought and thought, and changed their minds. And then the girl who committed su*cide, she was genuinely gaslit and manipulated by her family, not to mention isolated, and considered MC the closest person to herself, when she finally got the courage to talk to MC about the fact that she was married with a daughter, seek advice from someone she believed was wise, she was aware that she was being pushed into being terrible by her family, and at that moment more than anything, needed someone to help her dispel her family's influence, but what MC did was say 'we aren't compatible goodbye' in an era when that situation, of abandoning marriage for a diploma was so widespread, she thought that if she herself had been in that girl's shoes, she would never act like that. That mindset was also why MC disdained the other ones too, but she, who has backing, who has knowledge of the future, who has a space that spans an entire planet, who has a trade system space, naturally she could make a different choice, because the amount of options she has, it's so much bigger than what those girls have. She was able to cut ties with her family because she was alive for more than 100years, because she knew where her future leads, this girl did not, she had none of that, she was a girl with a personality that was a little soft and easily swayed, whose family knew exactly what to do to make her dance to their tune, with no other support system besides them, and a husband too far away to visit on a whim, whose letters never came and who never replied to her own. I pity them because MC was definitely in a position to advise them, to help them, but she didn't. She had her thoughts and her disdain and no words for them.

like the kid who was raised by his grandpa only to realize there was not really love for him anywhere because all the adults around him have either their own, more important families, or in the case of his mother, are chasing the long gone past and some ideal plan for the future.

It feels too black and white, like there is no middle ground. Any person who does not satisfy her will be her enemy. She completely disappointed with her parents (and I understand it) and decided to close her heart to them. She doesn't feel anything when her mother passed out. She lashed out on her husband when his answer doesn't fit her expectations. Then it really reach my bottom line when MC killed her adopted sister directly.
