Most stories start off with two people meeting cute, dancing around each other for a little while before falling in love and eventually, finally sharing that love in a physical sense. This is not that kind of story. One dude... LOTS of different women...
Wife cheats and leaves husband for her lover. Husband tries to resume his life and eventually contacts his old high school sweetheart. Fate intervenes to complicate his decision. Memories play a big part in the story: his and hers; good and bad; old and new.
