Legendary archer....sounds like...this is going to happen.....
Childhood friend consoles this archer, who's family/mother/father/sibling died because of some evil organization/governement/war, and then falls in deep love with him- he is too noobish anime male to comprehend love, so therefore he is oblivious to it. He decides to go after said organization/governement/war, and then turns out *zomg* there is a dark spirit of some sort behind it all- and then the anime continues from there...
Sounds generic enough?
