@Soo-ji_Queen I’m guessing that the prince “fell in love” with psyche so someone like Medea wouldn’t be able to become the queen. This would give him complete power over the kingdom and it would also give him a puppet of a queen. After all, Medea said something like “I just have to become queen” or something like that.
my understanding from those last chapter :
Medea is playing 4D chess
While the prince is playing 5D ! just then Psyche (aka new Medea wanna be) is trying to understand the basic roules of chess
but hey ! look at this ! Medea is actually playing 666D chess with Heli (best boy?) as the knight !! we can also assume that the cat is the real mastermind and he is controlling everyone !
anyway I think at this point our only solid point is that Helio is really on Medea's side.
