@Abiss I don't think the ML's attitude is gay, although I like the idea of sending the villainess to the other world, they still need to interrogate her, for example, to discover the whereabouts of that grimoire, to know if she has more accomplices, they should consider what happens if they kill her and the king is still under that spell or hypnosis. In that case they would have a problem, the prince would have to dethrone his father, and a civil war could break out.
