I don't think they died, guys. I'm sure people definitely call out for those two and the King will order the investigation. The prince will be the one who explain everything and demonstrate the potion. After that, the King will order to distribute the potion to all the people in the Kingdom. Then, everyone become kind-hearted and beautiful!
Happy Ending!
Does anyone know the title of this manga?

It's kinda confusing because they didn't express much about love but I assume that towards Hiroi, it's love. While Mine and Take it's more like "like".
