I think all three were wrong, the prince who swore false promises, the courtesan who didn't know how to distance herself when she discovered the truth and the princess for the murder.
Buuuuut, the prince deserves to suffer for many more years, it was so cruel for him to see the courtesan bleeding from the mouth after being poisoned and not show any empathy for the human being who kept him company for so many years.
It's a short but incredible story, worth reading.











I read the manga and then the reviews here, and I feel alone in my opinion. I really liked the story, I just can't say I loved it because some things took too long to be concluded and other things were too rushed.
But in the end, reading it was enjoyable and my advice is that everyone reads it to draw their own conclusions without the interference of anyone else's.
