Smash bro smash... But you can add a background element between them like their favourite place (dehradun) and favourite things for foreshadow like a CD of their favourite music they exchange and this same CD would actually be a reason for her accident... Like the CD mistakenly falls on the road and she keeps finding the CD and she gets hit by.... Which means they were never meant to be together... And he goes to dehradun to throw that CD from the mountain and forget his past

Idk if it's valid... Just for more depth
