Though Noah is literally a devil, I feel like no one within the world of the story would suit her better in the sense that both are afflicted by their immortality and have done/experienced things no one else could ever. Also, their end goals are similar, they just want to be away from humanity (lmao same tbh)--Noah by sleeping for eternity and Ellen by seclusion. Idk but it just seems logical for them to be paired for me.
Uh girl he would've been fine if you hadn't come back for him...
