PLEASE help me indentify a video clip
 

Hello
i don't know much of lyrics but...
The music video shows us a girl, short haircut, brunette, not very pretty. She is being recorded by a camera, it seem like her boyfriend is filming her, she is walking around in the nature, smiling to the camera etc, it is stylized to be an amateur video.
Generally song is being singed by a man, im not sure but i think we can hear an acustonic guitar in the background, its probably love song, its beautiful
all i can say about lyrics is that in the beginning of chorus he sings "you" and then it is followed by whistling or melody that sounds like whistling and then something like "tudumtumdum" and again something like "you and" or "you are" or smth like that and then again whistling. The song is rather not old, i guess i saw it about 2-3 years ago, maybe a bit more. Song was being repeated quite a lot on music channels in that time.

please help me, i'm looking for this song for soo long and still can't find it, maybe u know something..
