Haruki Murakami's novel "Colorless Tsukuru Tazaki and His Years of Pilgrimage" follows the life of Tsukuru Tazaki and his relationships and bonds with people he meets in his life - the group of five close-knit friends, his parents and siblings, his girlfriends over the years, and his friend in college.
Like most of Murakami's works, this one also has on open-to-interpretation ending wherein the protagonist is set to meet the love of his life and find out whether he is loved back or not. The story ends before that meeting even takes place. What must have happened? Did Sara say she loved him back as he hoped, or did she really have another boyfriend as he suspected?
What evidence do we have to suggest what it was?
