Forever and a day

"I will love you forever and a day."
Christa is dying and needs a heart transplant.
Joshua is broken over a gruesome heartbreak.
Christa, not being able to pay for the transplant, decides to make a bucket list.
Joshua, not being able to take the pain, decides to make the best of his life and do every crazy thing he can think of.
Neither thought they would be finding love.
p.s. Not good at summaries. Please read, way better than it sounds.
