A bit more about Etu's sexual desires. I hope the text is self explaining, otherwise I can explain more:
He only feels the deepest passionate connection towards a dead person when both had spend a lot of time before their passing. How they die is not very important to him but he has some preferences.
I wonder if the pain of loosing a loved one is giving him this kick, the grief you feel can easily be turned into something addictive like selfharm.
If I do any grammar mistakes have mercy, my dyslexic ass forgets letters or words very often.
