An angel's love (Genoa x nyo!Cyprus)

Set in a fantastic place which resembles both Ancient Greece and Ancient Rome , it tells the story of a sweet romance between a male angel(in my story angels actually have gender,there are both male and female ones they just aren't born the way humans do ) and a female human.
A young angel , Pancrazio(aph/hws Genoa) visits Earth for the first time but the humans he meets are so rude and cruel to him, resulting him on feeling so much sorrow. Later a young girl, Nausicaä(nyo!Cyprus) comes near him and helps him. The angel realises that the girl has such a kind heart and not all humans are selfish and cruel.
From that point and on they fall in love with eachother and realise that they are entangled in all sorts of feelings they hadn't bargained for. The real question is : "Will they be able to live their love , while being happy forever or it will end up as a tragedy that will forbid them from seeing eachother again?"
