yeah,this arrangement is dedicated to my little daughter sarah.my 7 years old cute little sarah.

she loves this song by taylor swift, and one time we were listening to it in the car and she said "dad, this is my favorite part... it's it's ..you know, right when the key change happends, and it looks like the boyfriend got scared of by the mean dad and he's never coming back, she's about to lose hope and all of a sudden he comes back and he says "hey I talked to your dad" and he pops the question, "go pick out a white dress"...anyway...

thats sarah's favorite part and when i got to that part when i was arranging that, i tried to extend that moment a little bit.
and it just felt like it should go to viva la vida,by coldplay,so...thats love story meets viva la vida.

补充一下，这个mean dad是男主角自己的老爸，不是网上传的“未来的岳父”，看过小说的就知道。
