They both need each other, he needs her to get over his father's death and she needs him for helping her reach her dream AND get over her father's death as well.
obviously, Death was a reason why those two, who seemed to not stand each other [ but nothing is as it seems]
will get closer and closer so rapidly that YOU as a reader, them as humans and me as a writer will lose our breath marvelling the art of true love.
-It's a short novel. ten or less chapters!-
