So frankly, I quite enjoy this. The MC is fantastic. He's a bit independent, very intelligent without falling into the 'nerdy' or 'geeky' stereotypes, rational, and caring. To be blunt, as a MC, he's exactly what i want to read about. The female lead is equal parts adorable, intelligent, yet the main source of the 'fish out of water' trope that this story is based upon. The potential romance is great, the humor is nice without being overbearing or too lacking. Honestly, the story hits a lot of sweet spots - not too much, not too little - in a lot of categories.
What's weird to me though, is where the author is going with this. I have no complaints really, but it's VERY slow burn, and yet not slice-of-life? I mean he's not even married to her (yet?) despite the title, and the central issue brought up early on is that she has no citizenship registration, which in china (and elsewhere tbh) is a major issue. No job, no driver's license, can't get noticed by the government, etc. I'm expecting that there will be a fake marriage to somehow make her legal, which given the slow-burn romance, will eventually turn out real.
So yeah, no complaints, but it's so... slow? The MC is a bit of a polyglot tbh, and he really prioritizes giving her a full education on modern life, not just teaching her little bits, but so that she can make her own choices, sprinkled in with a bunch of commentary on society. A little overly perfect? Perhaps, but way better than doing it for sketchy/scummy reasons, or having a disgusting or creepy MC. Please no complaints on a GOOD MC!
But yeah, my only real issue is how slow it is, in terms of the story's total lifespan. Like 40+ chapters in, and still no marriage. The weird thing is I can't complain, because I'm really enjoying the story, but like... is the author planning on hundreds of chapters? There's absolutely no other female characters, and no love triangle or anything like that. Just curious on what the future plans are. Who knows!
