Have Pure O OCD specifically on this topic, so will go into more detail here. Constantly believing that no one will love or desire unless am dead. Want to leave a wonderful corpse so a necro will be able to use as seen fit. So in other words, really putting in efforts to be the best corpse can be. Necro will be perfectly a-ok for me so long as am desired and cared for like the other corpses and dead people. When looking at them, think "Damn, wish to be as cared for as they are."
TL;DR Necro styled Pure O OCD haver wishes to be a good looking corpse so a necrophile will be happy with self since undesirable irl
