This is a cracky idea but: what if the Corinthian is a group project between Dream and Desire before their relationship turned hostile? Physically Coco and Desire look alike, and Coco has that whole 'lust and desire to live' thing. Endless custody battle, creator alienation, any kind of petty family drama x1000 between two older than dirt beings who should really know better
maybe more cracky if this was someone's terrible idea for a get-along shirt. remembering how things went with alianora (and, well, all the times desire's fucked with his "love" life), morpheus is all, "i'm gonna make a weird dude who won't expect to be loved forever but will expect to be hurt and/or ignored and take it tyvm." desire pumps so much desire in him without even looking that the corinthian's humping morpheus's leg the second he's brought to life. they bicker so much over changes to make after beta testing that neither notices that he's run away from home.
