What do you think about the Hakkai-Kannan pairing?

Question

I was surprised to know that Hakkai and kannan are sibblings, but don't you think it's just alright for them to live in the same house and treating each other more then sister-brother relationship?

Answer 1

it's not right for them to have a relationship because siblings are supposed to do their jobs as siblings which is to annoy each other not have a romantic relationship.
