The new teacher is suspicious, but we'll see where it goes. Maybe he was just convinced because she is friendly with a commoner, or maybe he has an agenda. He probably has an agenda 😁
I have to agree that this remake feels more interesting. The problem with the original story is that by the time Katarina enrolls in the school, everyone is already in her harem so there's no tension at all, because you know nothing can possibly go wrong.
Here it feels like something bad COULD happen, thus it's more interesting.
