One thing I’m a bit disappointed about is the lack of world-building beyond the system. The goddess just appears, gives the mission, and disappears. I’d like to know more about this multiverse or the rules of luck collection. The story is focused on the romance seduction, but I think adding some lore snippets would enhance the depth without slowing the pace.
The whole childhood sweetheart backstory being explained as "we became sworn enemies the moment we learned we had to get married" is such a fun twist. Usually, it's all "we loved each other since we were kids," but here it's pure mutual annoyance. It makes the eventual love story more satisfying, I think.
I love the small worldbuilding details like the "blackstone" currency and how mining caused pollution. The half-dead creatures being a result of death energy from the veins is a cleverer take on zombies. They're not just magical undead; they're an environmental hazard. And the fact that living miners can mutate too adds horror. Karl better be careful—one wrong step in the mines and he could become one of them.
The trade area is mentioned but not used yet. I'm curious about how she'll trade later, especially with water surplus.
'Your brains really worry your Father here.' This line will be stuck in my head forever. It's the weirdest translation for the 'worrying father' trope. The friend interactions feel very authentically translated from Chinese youth slang. 'Cui Cui, that hurts, you trying to kill me?'. The banter is fun and gives a sense of a normal life before the insanity starts, which makes the world feel bigger.
