The main selling point of the novel is the interactions between the female leads. Starting off with Zhao Qingyu never getting a chance to be with Song Xuyi works extremely well as an opening arc for establishing the yearning the antagonists of the worlds have for Xuyi, and seeing Xuyi gradually being 'captured' in future worlds is a strong emotional beat. However, after this meta-arc ends, Xuyi's relationship with the antagonists in each world stagnates and the relationship between the two becomes rather repetitive. Personally, I didn't really notice this until the real world arc, but your mileage may vary.

As for the plots of each world, they're strong enough when the focus isn't on them, but they're not capable of standing on their own. It's very common for side characters/plot threads to be introduced that feel like they should go somewhere, but ultimately are simply never followed up on and simply cut off. This is usually fine since the focus of the book is moreso on the interactions between the FLs, but occasionally the balance between FL interactions and plot ends up being broken. Personally I found the last world, for example, to be far too light on the relationship dynamics that the author is good at writing and too heavy on the overall plot which was rather unexciting, which made it a rather boring read for me.

Generally, the actual main plot threads tend to resolve well enough, but unfortunately the same cannot be said of the FL interactions. The majority of the time, confessions act as the ending of the world arc, with only short, impersonal blurbs describing what happens in the lifetime after. Many times, this is made worse by the fact that the confession is also when Xuyi realizes her affection is returned and/or represents a major shift in the FLs' relationship, which makes their arc in that world feel incomplete. This sort of incompleteness works well for the early bad ending arcs, but is quite unsatisfying for the majority of later happy ending arcs.

The real world plotline suffers from very weak connections between the hints given in the world arcs and what the real world plot actually was. It felt like the real world plotline was ultimately scraped together at the last moment from hints dropped in the story beforehand instead of the other way around. In theory this could've been patched up somewhat by instead leaning on the character meta-arc aspect; Xuyi is said to have gone through an arc and, in each of the worlds, learned to live for herself. However, I personally did not really get the impression that Xuyi needed to learn that lesson at all, let alone that she actually did; in the first world, she learned medicine pretty proactively on her own inititive, for example.

If any meta-arc existed, it would clearly be one to address her inferiority complex toward Rong Yu and having her become more proactive in a romantic sense, but ultimately the real world arc simply repeated the plot line of Xuyi not wanting to get closer to Rong Yu due to excess concerns, Rong Yu lying to get closer to Xuyi, and eventually Rong Yu snapping and revealing her feelings for Xuyi. The idea of making up for regrets that Rong Yu brings up to get closer to Xuyi was interesting and could've made up for the repetition, but was basically not executed on at all. The real world plotline doesn't really hold up on a plot level either; the link between the chips in the last world and the real world plotline was simply introduced too late to really feel premeditated, and the rest of the plot details just completely felt like they came from absolutely nowhere.

For a few more specific examples that cover quite a lot of the above criticisms, the zombie world makes some odd choices; why did Zhao Miaomiao recovering her memories specifically trigger the main system to do something? What was even the point of Zhao Miaomiao recovering her memories from a story perspective? Why did the author put off the relationship redefining moment of Ye Shuiyu post-recovering 18 years of memories by having her lie? It makes sense from a character perspective but it doesn't make any sense from a storytelling perspective. The relationship redefining moment is instead tossed into the middle of the impersonal "and then x happened" blurb at the end where it definitely can't make any emotional splashes and won't let us see any of their thoughts.

To say something positive though, I did think some of the callbacks, specifically the system being based on her cat and a dress Rong Yu wore in world 1 being one that Xuyi bought were good anchors making the real world plot feel more connected to the small worlds, it just wasn't enough.

The extras are a mixed bag. The vampire world extra is fine but suffers from the exact same issues as the rest of the worlds; it ends up feeling less bad since the accelerated pacing means that the abrupt conclusion has less to fail to live up to, and admittedly making the abrupt conclusion a punchline was decently comedic, but it's still somewhat disappointing to be hit with another world with the same strong points and weaknesses. While I liked the IF childhood extra, it felt somewhat muted by my problems with the overall real world plotline. Still, it served as a good wrapup and finale for the book, and the different relationship dynamic was refreshing to read.

But around the middle it became a bit too draggy, you can tell what the author wants to portray and it does at the end of each world, but ending of each world around the middle to the end felt very forced (?) more like they were trying to end it in a couple of paragraphs which is sad to see.

as much description of how the fell in love in every world like the first and second.

such as coming up with a cure for the sleepiness disorder, eliminating gender bias of omega and beta groups, reducing world hunger with modern farming knowledge, etc.

1. Fan and actress - sleepiness disorder/narcolepsy

2. Alpha and omega - slowly dying drug

3. Neighbour - xx

FL turned out to be some alien with a microchip and was once saved by MC when she tried to escape from the lab but.... both lost their memories but still retained the feeling of secretly liking each other. She was exploited and her memories came back when she turn 26 thus she devised a game with multiple small worlds to train her mind power? While taking out the ppl who imprisoned her.

She confesses everything when she saw the divorce papers in MC's hand. Yeah then HE. Sigh.
