it's always funny to me when ppl act like it's somehow incestuous for characters who consider each other found family/chosen family/whatever u wanna call the trope to date each other, and it's funny for many reasons, but most specifically it's funny because irl when you meet a person and get really attached and decide that you want to be family with them, there's a very popular legally recognized way of doing that & it's called marriage
Marriage promotes incest because then you end up having sex with a family member
