My Impression (which is just fangirling, so feel free to skip)
Solid 4.5. A great first novel with excellent world-building, minor plot holes, and superb characters and character development. It’s the perfect blend of a shounen/BL novel, incorporating a wonderful amount of humor to lighten the severity of the situation at times. It can really detoxify your stress in an instant. Do keep in mind this is a feel-good novel, so don’t expect the characters to walk a thorn-filled, anguished, and deeply realistic path, though they will have their fair share of struggles. Anyways, back to the objective rating of this novel (I’m going to add no spoilers, so pardon me if my review is vague)....
Characters
The main character (MC) Xie Lan and the male lead (ML) Luo are both strong in their own right. Xie Lan has a straight-man persona that can get you laughing, and his way of handling high-stress situations showcases his capability and level-headedness. His poverty is also quite humorous, and I love how what was once considered a flaw in his reality becomes his strength in the Advent World (in multiple, sometimes questionable ways). He doesn’t run away from anything, nor does his personality change drastically when he gets together with Luo (like becoming overly shy or blushing all the time), which only boosts his character points to a 100/10.
On the other hand, our dear Luo is not an omnipotent ML, as you often see in escape game novels, and is ironically human in many aspects related to strengths and weaknesses. I can’t really give away much about him because he has a pretty mysterious persona in the summary, but just know he is one of the healthiest MLs I have ever seen, and you are guaranteed to love him.
Another bonus point to the character section: the author develops the side characters wonderfully, each with their own growth and personalities (instead of mindless MC followers) without taking away focus from the main plotline—quite commendable, considering I get very annoyed when authors try to develop side characters because they often do it poorly and detract from the original story. So, you’ll get a dash of side characters (that can actually get you attached to them) but not to the point where you will be impatiently scrolling, trying to get back to the scenes with the ML and MC.
Haha, also, the number of times I got close to tearing up and then one of the characters ruined the mood with their endearing straight-man personas really did something to my heart.
Romance
In terms of their relationship, what I love the most about them is that it barely follows any of the clichés. The author injects originality into her characters that allows you to stop predicting their actions—which is the ultimate refresher in my opinion.
Their relationship is built on trust, and there is no useless drama to prove how strong that relationship is. There is endless respect between them when faced with each other's actions, and both are capable of standing their own ground. There’s no dynamic such as "one strong, one weak, and the strong constantly saves the weak." If that isn’t a sign to pick up this novel, I’m not sure what is.
Plot
This is going to be very short because I want you all to go into the novel with surprises, not spoilers. However, the author develops the plot well, with minimal plot holes and a story that engages you and makes you question what happens next. While I believe the author had the potential to further enrich the plot, she did well for her first novel.
The author is also very talented in setting the scene but leaving just enough to your imagination while not transcending common sense (at least not obviously in her novel—common sense is one of the main strong points of this novel). I also appreciate that she didn’t make the monsters omnipotent, emotionless beings; instead, they are an existence with their own character and flaws. Additionally, the ending wasn’t anticlimactic and rather built up the suspense to the point where my eyes were glued to the screen. Not a spoiler at all, but if you like music, Lacrimosa and Clouds (Huma-Huma) really fit the near-ending of this novel. Hey, I like listening to classic, creepy music while reading escape game novels—don’t judge.
Conclusion (TLDR)
Read it.
