Lykk Li - Wounded Rhymes

I Follow Rivers (Director: Tarik Saleh)

The guy was a soldier. The woman in black was someone he killed and felt regret for killing. He is being chased by the memory of her ghost until he can't go no further and relents to the sorrow of his sins. Her kiss which he is intitally unwilling to accept seems to present forgiveness, but the last glance lets us know it's the kiss of death.
