As said in the title his bride to be dumps him at the altar and runs away with the h boyfriend.
h decides to move on with her life and ends up in an apartment in manhattan where H is her neighbor
He is a successful doctor and she is a famous painter with modest upbringing
H brother gives up med up to become a singer
H mother manages the hospital where he practices and is a huge fan of h work. She hires her to do a wall there.
