Ding Mom Arc:
Ding Mom was slowly losing it. Living each day, alone, when even her neighbors despised her, she would at some point erupt. Qiao Nan could feel it after her last conversation with Ding Mom, so after a talk with Soaring, she decided to let Ding Mom move over to Qiao Zizi's old house.
Before, when Qiao Zizi had to sell her house, Soaring heard about it from someone. Knowing that the house truly should belong to Qiao Nan who paid for it, he ended up buying it. MC only got to know about it later on.
Using that fact, Qiao Nan now wanted to have Ding Mom move over there, hoping that a new environment, in which her neighbors won't be biased against her, could do her some good. I'm pretty sure Ding Mom wanted to cut herself off from her 'old worries', so she even ended up changing her phone number so that some people (Qiao Zizi) couldn't contact her.
Qiao Zizi Arc:
Qiao Zizi has been living in Chen Feng's house for some time now. As always, her life's priorities are messed up. Instead of thinking about her kid and how to compensate him her lackluster behaviour before, she starts thinking about how to milk him out so that she can live comfortably.
When Qiao Zizi 'accepted' Chen Feng's custody from his grandparents, she thought that they would give her some money each month to pay for Chen Feng's daily life, so she could use it for herself. However, Chen family had some experience on dealing with her, so knowing her, they decided to put all the money directly onto Chen Feng's hands.
The house was nice and all, but our princess Zizi needs to eat. When Chen Feng was at home, he would buy some food and cook, so both of them could eat it. However, for most of the time, he would stay in his school's dormitories, coming back once per 2 weeks.
When he's not there, there's nobody to take care of food for her. Ding Mom for most of her life wouldn't let her do any house chores, including cooking. After she married, Chen family had hired a housekeeper, so she didn't need to learn how to cook either. Now, with nobody to take care of her, she had an issue. Obviously, she wouldn't think about learning to cook now, right? She'd prefer to order takeout food, but that needs money, and she doesn't go to work.
Chen Feng wasn't giving her enough money for that kind of spending, so she wanted to take away some of Ding Mom's money. After all, Ding Mom was getting some money from Qiao Nan each month, and Qiao Zizi thought that her mother is already old, so she doesn't need it. Yeah, her logic coming out as always. Ding Mom already moved, so Qiao Zizi called Qiao Nan. They had an argument, and it ended up with MC telling her that from now on, it would be best if they treated each other as strangers, and that Zizi should not call her anymore, since she won't pick up anyway.
Chen Feng + Jiajia Arc:
Huahua's daughter, Jiajia (pretty sure that's just MTL, her real name should be diffrent), got into a college in the capital, so she moved together with Huahua to the capital, so the whole family was reunited.
I think there was a time skip somewhere in between, since Qiao Nan's children are already 5y old.
Chen Feng came to the capital to study as well. He's pretty diffrent from his mother, so when he came to the capital, he asked Qiao Nan to meet him and thanked her for all the care she showed towards him when he was growing up. After all, if not for her, and later his grandparents, he probably wouldn't be able to live through his childhood, since his parents are Qiao Zizi and Chen bastard .
Anyway, Qiao Nan talked with him for some time, told him to just be himself and not listen to other people's nonsense (Qiao Zizi). She also gave him her phone number, so that he can call her if he has some issues in the capital.
Later, he asked her about her kids. Chen Feng was truly curious about his little 'cousins', and since Qiao Nan could see that he was sincere when he asked about them, she showed him some of their photos/videos, and said that she wouldn't mind letting them meet in the future.
When he finally met the children, Jiajia (who btw. was a big sucker for the kids), was scared that his personality would be similar to his mother and he would treat the kids badly, so she came to the meeting as well.
I think here we get another time skip. Qiao Nan is already 50y old, Soaring is 55y old, while their kids are 10y old. Unfortunatly, but ML's parents died. The kid's grandmother just died, following after her husband who left 2y earlier.
On the 2nd day after ML's mother died, Qiao Nan got a phone call that Qiao Dad was dead as well. Also, as a funfact, I'll add it here: Chen bastard died 3 years ago.
Jiajia and Chen Feng just came back from studying abroad, so they split themselves between the funerals. Jiajia went to help Huahua and the rest of the family to prepare the funeral for ML's mother, while Chen Feng went over to help Qiao Nan with Qiao Dad's funeral.
Chen Feng and Jiajia turned out to be lovers. Before, thanks to their interactions with MC's kids, they were meeting more often, and slowly built some feelings for each other. Chen Feng was a pretty shy person, and was a little scared that he would mess up his friendship with Jiajia if he confessed and she rejected him, while Jiajia felt that the man should confess, so they ended up in a weird situation.
When they were picking college, they tactfuly picked up the same college abroad, and in the end even ended up renting a house together. Chen Feng was pretty popular with ladies, so quiet a few times some of them would confess to him.
Jiajia was slowly getting both tired and anoyed by this, so once she couldn't hold it anymore, and told the lady that was confessing, that Chen Feng was her boyfriend and they even lived together. From there on it went pretty smoothly, and now they are thinking about marriage.
Qiao Zizi, hearing that her son came back, wanted him to go and live in Pingcheng with her. He didn't approve of it, and his grandparents told him to stay in capital. Qiao Zizi got to know it, so she ended up asking him who's more important for him, her or the grandparents (suggesting that he should live in Pingcheng if he chooses her). Yeah, he didn't pick her. She was mad, but he just reminded her of who took care of him when he was younger, and that even if he has no feelings for her, he will still send her some money each month, so she doesn't need to be scared.
Later on, she had some ideas about moving to the capital and living with him, 'taking care of him', but he quickly kicked this idea out of her head.
Anyway, we've had another time skip. 4 years later (MC's kids are now 14y old), it's finally time for Jiajia's and Chen Feng's wedding.
Qiao Zizi was unhappy with her daughter-in-law. She was dreaming of having a weak minded daughter-in-law, that she could control and take advantage off. Jiajia, like her mother, was pretty fierce, so Zizi didn't like her, even more with her connection to Qiao Nan.
When Qiao Zizi arrived in the capital for Chen Feng's wedding, and saw his house, she wanted to convince him to dump Jiajia and live with him in that house. He told her that the house was paid 50/50 with Jiajia, and dragged her to an apartment he rented for her. If she wants to stay in capital, she can, but not with him.
During the wedding, Qiao Zizi tried to make some trouble for Qiao Nan, blaming her for Chen Feng's attidute towards her, but Qiao Nan pretty much ignored her, telling her that everything she does has its consequences.
Ending Arc:
And ladies and gentleman, we have another time skip. Qiao Nan is currently 65y old, Soaring is 70y old, while her children are already 25y old, from what I understood they are already out of college.
Chen Feng and Jiajia also have children now. Not sure about their gender, but their oldest is 7y old (Chen Peng), while the younger one is 4y old (Chen Xin).
This year, Soaring and Qiao Nan slowly left their house in the Capital, and moved back towards their ancestral home, so that they could spend the rest of their lifes in peace.
A year later, they've got a suprise visit from their children. Turns out they want to get married, all of them. Soaring was a little worried, since he didn't want them to force themselves to marry to fast for their sake, but they convinced him by saying that they were dating their counterparts for over 3 years now.
Well, Qiao Nan's daughter was. Her sons were dating for over 3 years, but not exactly staying with the same person for 3 years. Anyway, they took their time finding the right person, and in the end, they decided to get married at the same time, so that it wouldn't be to hard on their parents. They also decided to hold the wedding in the city that Qiao Nan and Soaring currently live in, so they wouldn't need to travel back and forth between capital and their home.
When Qiao Nan and Soaring later met their kids choosen ones, Soaring had a pretty good impression of his new daugter-in-laws and son-in-law. His only hope now is that the couples can have a good life, like he does with MC. Later on, their kids had their wedding and life continued.
And we have arrived at the end of the novel. Aside from that, there are some extra chapters, but I only skipped through them, so I'm not gonna write any spoilers for that. Anyway, there's a short story-like confession from Qiao Zizi, and a little longer, like 35 chapters long, story about ML's parents.
