• (if it ain't your love) i want blood from you

(?) Serial killer's first crush. For the first time, someone has caught D.O's attention in an "I don't want to murder you" way. He tries his best to woo Chen with special methods (gifting severed heads/limbs, offering to kill people Chen doesn't like, burning things in Chen's honor, etc.), all the while keeping his disturbingly blank face.
