This is tragedy to everyone's involved. It's just painful.
It's rare that I can sympathize with every character involved in the story. Not that I condone their behavior, but their motive is so human. The author treats them respectfully and gives them characterization that they deserves.
Also, the author clearly understand the critical role of world building to create much more believable story and to make the plot runs smoothly. Honestly, I really love the story logic in here. Yes, there is soft magic, and as a reader, from MC POV, we don't really understand the magic system in this story. But the story clearly explain the law of causality as a basis of all that's happening in the first place. And that's really impressive for Isekai shoujo like this. I just love the world building here.
