How did it get four stars? Well, it's webnovel so looking at the scores doesn't really have any real purpose.
It's mediocre. I can't really get into story, MC doesn' really make me feel anything much and even then it's more of an annoyance, some problems with grammar (that may be on me, not native speaker) and weird formatting here and there. It would be better if it made me interested in the story, but I had to force myself not to skip it and scroll down for a moment just to not have to read something annoying / boring. Overall? 4.5/10, maybe 5/10, wouldn't really recommend, but you may want to give it a chance if you don't have anything good to read.
