I thought that the fact that demon's can only love their bride was a well known fact? Or didn't Toko explain this in the previous episode? In that case, why does Yuzu easily believe that Reiya could have a lover? And it also seems a bit far-fetched to believe his secret lover would be his assistant with only dodgy pictures as evidence in my opinion. Yuzu's birth parents are also starting to become too unrealistically delusional that I'm starting to think they're the least intelligent in the show. Not sure if it's because I'm missing something, but not the best episode so far.
