I dont know how luck there will be in someone knowing this but here's a shot. 3e4i5o

I dont too much about this Japanese MV besides the fact you got a dude who like to takes photos of sunflowers, and there is a girl involved in some way. It is fairly old and is a ballad as far as i recall but i could be wrong. The major defining feature i think is accurate is the guy wears a yellow headband.

any help identifying and locating this mv is appreciated, and many internet points to be had
