Glad we don't have to worry about disgusting incest in this. Unfortunately we have to deal with Elisa, The Human Enigma. Your sweetheart, who has miraculously survived, has turned down a plethora of attractive women to be with you and you turn him down. I get that there's a time and a place for these things, but she'd rather he be with someone else because of some weird hangup she has. Probably something like, "I don't want our relationship to be based in obligation to duty," but I guarantee none of the other girls will see it that way. To them it's a moment to bond through adversity.
Anyway, rant over. Glad we're avoiding the sister and the little girl, though.
