Honestly this backstory just made him seem even creepier to me, but at this point in the story, eh, whatever. It's not like him being a godawful stalker is new or anything.
So who
is going to take this god bloke up on the immortal-dragon offer? XD
@Manchura: Since I am a pedant: Technically technically it has not, because, as-portrayed, he didn't show any romantic interest as an underage kid, only later—and obviously neither did she when he was a kid, for all three seconds of their interaction. It is, at worst, an age-gap romance, and weirdly because of timey-wimey reincarnation stuff and comas, possibly one wherein he is the elder.
Not saying it's not creepy, it is, just for other reasons like him slowly falling in love with some dead woman and semi-committing-suicide to chase after her. These are not things stable people do.
