It's quite good, without me dwelling on its uniqueness. The core concept of the story is solid. As a teacher in this situation, it offers a refreshing perspective, and I find it enjoyable. Up to 30 chapters, the first 20 mainly focused on world-building and introducing key characters, which might be slow, but it's not overwhelming. Don't expect immediate excitement; this isn't your typical fast-paced adventure.
The main character is quite calm, cautious, and passive, common in many Japanese narratives. However, his maturity suggests he's not a doormat. As for the supporting characters, their interactions with the protagonist are there, but it's too early to form a deep understanding beyond them being decent and realistic.
Overall, it's not a bad story, but it's too premature to make a final judgment. The fresh perspective and the high-stakes setting promise plenty of action and development. Plus, being tagged with a harem theme appeals to me as a fan. Given the well-done translations and few major issues, I'll give it a 5-star rating for now.
