I don't think you're weird, it's kinda normal to feel that way since they grew up as siblings.
I also feel weird but I'm kind of used to it. Most Telenovela/drama in my country has pretty much used the grew up together sibling but not related ended together or love each other but ended up breaking because they were related...

Is ANYBODY else mad uncomfortable or am I being weird ╥﹏╥ just can’t get behind the sister but not sister thing
