Well, the ppl with morals value to stand surely against the both of them in relationship. Even though biologically, they're not related so the problem where siblings marriage brings wouldn't occur, like recessive gene etc (omg stop lyn). But still shouldn't blame some ppl coz those morals already rooted in their head.
ANYWAY they're cute, even the knight admits it (▰˘◡˘▰)

Look here people! love is love! There is no right or wrong if the two people love eachother unconditionally! So incest, age gap etc fuck everything that is blinding your eyes to see what the two people share with eachother as feelings and emotions! Just concentrate on their ways of loving eachother.
