It's a nice read. A great plot, smart MC, and unique world background. The MC is out to achieve a significant goal which is great to read. It also has a great romantic plot. Summary: It's worth reading.
Thanks for sharing this with us Author-San.
The writing quality is the best out there. I see no problem with the grammar, but people might say I have low taste in grammar. That might be true, but as long as I can read the text, it's enough for me.
