So in chp 4, the dark Mitsuo stabs himself after the light one watches a disc of the dark one getting raped. Then he wakes up in the hospital and he tells the light one that's he been reborn and kisses him. Okay. So seeing your "dog" (obviously more than that) see you being raped triggers you to stab yourself. What, you're filled with feelings of shame and embarrassment (of how low you sank) that you can just die (literally)? I'm just amazed at the self-harm that these people go through. They can never do it the easy non-violent way, can they? (then there wouldn't be much of a story)

It's interesting that this chapter starts out with the dark Mitsuo having sex with a prostitute, while the light one watches TV as he leans against the bed they're doing it on. Sort of like overcompensating. . . the dark Mitsuo reaffirms himself that he's still in control and denies the feelings of the light Mitsuo through hetero intercourse (might be a stretch in my thinking). Well like the prostitute said after having sex with the dark Mitsuo, they are a weird pair.
