"incest" as in "noone understand me the way you do" and "noone can hurt me the way you do" and "I loved you since day one and I will love you till the end of time" and "I hate you in such a personal, visceral way that only you can make me feel. You hurt me so much yet I still long for you and what we used to have" and "you annoy me so much but I don't know how to define myself without you" and "you're my home, my world, my safety net" and "how can something that's supposedly so wrong feel like comfort and safety" and always "you're part of my flesh, anyone who manages to tear us apart will leave us mutilated and bleeding and we will never be whole again".
Incest can fit all of these contradicting emotions between two people in one lifetime. The blood pact is inscripted in their DNA after all.
