Aside from the fact that MC's family is perfect for no reason, to the point of being so boring they have no point in their existence outside of being the anchor to MC's world. The family's connection to the MC is so questionable - they chose to be with the boy who is their flesh and blood over the one they spent 7 years of their life with for what? This could have easily been a reason to flesh out the family's characters; MC's younger brother could have been angry or upset about being raised alongside a fake brother but instead he simply chooses to move on in the matter of a few chapters; the family doesn't allow for MC to choose to go back instead fighting to keep him which is another point that could add drama, tension, perspective, and more nuance to the story but instead is solved in the last chapter with ease. The mystery behind the switch of MC is never explained, and the method which the older brother uses to go in between worlds is never mentioned again, the ending of the novel was so dull because it read like a large info dump with half the information missing. Speaking of the older brother - the entire point of his character was to solve MC's problems. He's the perfect character, and while that would have been acceptable had he actually been a character in a novel like the MC assumed, him not being one just downplayed the seriousness of every issue faced by the MC (since it was obvious the perfect older brother was just going to solve the issue).

Seriously, the idea behind the characters being switched and having to live worse/ better realities than the one they were supposed to is smart. It's an intriguing plot line and really would make for some interesting characters and morals but instead we get a 'and they lived happily every after' ending with numerous loose threads.

there’s no explanation between how a 7-10 year old kid not only knows how to travel through bodies and worlds I also don’t like how they do it. If they knew Lin shen wasn’t the same one why didn’t they explain everything in the beginning? It would’ve been much better than letting him sit there confused and not knowing anything. Second of all there’s no backroads about the other Lin shen how does he know how to switch worlds and how can he still know how the Lin shen of the other world is being treated. Third how the heck does Lin Yuan become Yan shuo it just doesn’t make sense to me because if they knew how to transfer him over he should’ve been transferred back a long time ago. I feel like the MC Lin shen is a just a puppet whose been going along with strings someone else pulled for him. Don’t get me wrong I loved the story, I just thought that Yan shuo would’ve turned out to be the ML after Lin shen went back to the world and what makes me even more sad is that the end there’s no follow up on the other Lin shen. I gave the story a 5 stars but if not for the MC and ML I would’ve given it a 3 1/2 or 4 1/2 stars because the ending just left so many questions unanswered and a story should never have questions unanswered in the way this story did because it ruins the original built up vibe

I'm more curious about the other-MC that went to the real world. His relationship with the novel-older brother sounded more interesting to me. Especially since the novel-older brother said he wouldn't leave other-MC alone and could travel to the real world for a short period of time.

frankly speaking I wish the author can dive more into the otherworld lin shen's story. During the last fifteen chapters or so, as tidbits of his story is unveiled, one can't help but be curious about him and his relationship with lin yuan. I actually want to read their story if the author will write it, as it seems to be interesting.

Also, the explanation of Novel!Lin Shen and Lin Yuan' relationship was very vague. According to what it's explained, their relationship is a romantic one, but the author choose to make the MC uninterested towards the truth because 'it's their things' and 'he shouldn't meddle'. That really left me unsatisfied lol.

Although in the end Lin Yuan said something that implied he would visit Novel!Lin Shen in his world, but again, it wasn't explained how can he even do that.
