From the very beginning, as the title; in the introduction to the novel; and as a central idea, the novel is set up for the reader to question, "What exactly does Qizi mean?" In order to find the answer to this question, we must first understand the setting.

Thankfully, the novel does a superb job of pulling you into its world. As I was reading, every time I questioned the setting, the author would find a way to answer. Whether it was by giving a lecture, going on a field trip, or whispered rumors, the author finds interesting ways to give us information.

The pacing of the novel is superb, yet feels a little too structured. Whenever something bad happens, you know that there will be something sweet and fluffy to soften the blow, yet when it becomes so sweet that you can feel your teeth rot, you know that a bitter segment is coming up.

Within this somewhat rigid formula, the author is able to tie up any and all loose ends. In fact, the last segment starts over from 4000 years before the main characters meet. That doesn't mean this novel is perfect. I did have some questions regarding the choices some characters made, their logic, and a few tiny OOC moments.

I was also disappointed when I got to the end because it felt rather flat. I felt like there was quite a bit of build up for it to end in a way that didn't get to display how the main characters grew to love and accept each other.

After all, growth of the major characters was also a huge part of the novel and it does a good job of transitioning the main couple from rivals to friends to lovers. I really liked how the side characters influenced them. They took other people's experiences as life lessons and used it to grow as people, adding a touch of reality to this somewhat fantasy sci-fi setting. Again, I did feel that some parts were kind of anti climatic since they were written off as "this is coded into our genes and we can't fight it."

Personally, I feel like some of the central themes in this novel include the questions "What is love?" and "What does it mean to be human?" Once you find the answers to these questions, the main question, "What is a Qizi?" can finally be answered.

Armed with this knowledge, Ling Xiao and Ying Feng were able to overcome the unfair relationship between Qizhu and Qizi and develop a love that could surpassed the system and overcame all obstacles. It set an example for an entire planet, if not the universe, and they overcame space and time to come together in the end. Their love lasted 4000 years, and may continue another 4000.

However, the side characters can't be forgotten either. Each couple had a different form of love that progressed very logically. One way or another, every single character was motivated by the word "love". Every action, no matter how atrocious or benevolent, was done in the name of "love". I like how the author explored the different kinds of relationships that can be formed between two people.

the whole myth of Tianxu and how the system of Qizi/Qizhu come to be

where you fight to the death against the one you love.

They mention things like reincarnation and how when people in this world die, their spirit goes to the lighthouse or something, but it feels less like an integrated part of the story, but more like the author put it there for fun when they remember, and as a ploy to make it so that the MC and ML are actually soulmates in their past lives.

They snuck into the highly protected facility that all of their people go when the die and get reborn, and hacked into the computer there in a sealed off room that wasn't locked or anything

But the saddest thing is that it actually showed promise at first, but quickly fades into something lackluster.

(ノಠ益ಠ) ノ彡 ┻━┻

BUT, I'm not done yet, turns out EVERYONE WERE ROBOTS ALL ALONG. And what do you know? The main leads were soulmates in their past lives. Wow what a shock, a completely unexpected outcome, my eyes are burning from the originality.
