Kinda like the soul got separated from the body, even though the actress has the looks it's not her, but how cute are the origin story of so so??, a puppy saved and then becoming the guarding of her(the soul) and followed her when she reincarnated
blonde guy isn't even an angel . he's just an ordinary human born out of angels. Seems like ml is the only one who's lived for years while the blonde and so won are reincarnations (guess because they died in their past lives except for the ml? and the other characters from their past seem to have their memories intact in the present as well). If there's even an angel in the story, I'm still standing behind the theory that fl might be one because of the hints that his dad went to 'heaven' as well as supplemented with the fact that she can also see supernatural beings.
so let me get this straight: the blonde guy is an angel and doyah is a demon and they both have lived thousands of years and now they're recalling bits of their memories of this woman who apparently is so won's reincarnation (???) but at the same time, she also looks like that actress girl??? so that woman reincarnated into 2 different people??
