>>48445915I agree, in real life a more stable relationship is achieved with a partner with affinity, common interests, and good compatibility, but when it comes to fiction that would be boring for the viewer who seeks conflict, drama, or comedy. This is why dysfunctional couples are so popular in fiction.
But if I had to choose a partner for Ash as the end of his story, I would choose Korrina, their interaction is fun, also the blood of the Aura Guardians must be perpetuated.
