They don’t share parents and as far as we know he was never treated as someone from the family and even hated his non related father and sister for some time so I wouldn’t say it’s incest
Its not incest but they basically grew up as siblings and they still say brother and sister. Also completely agree with op, it really ruins a good manga
But they never grew up together though since Juliette was sent away from a very early age to train as a sacrifice and Sigurd never really had proper interactions from both father and daughter in his childhood up to adulthood. So I think I can let this one slide (づ￣ ³￣)づ
This ^^
I dont know emotional incest always gets me like it did not need to happen but i will continue cause i love the MLs and the other characters
if i had a dollar for every time incest has put me off from a manga
