Red Strings of Yggdrasil (слэш)

Loki’s hand goes instinctively to his fingers covering over the red string that has been tied around them for the majority of his life. He can’t feel anything, of course; it isn’t a physical cord, but a metaphysical representation of the entwining of his soul to another. A line that just trailed off into the distance, or had done, up until a moment ago.
When Loki finds out after the battle with Thanos that his string leads him to Stephen Strange, Sorcerer Supreme, he's darkly amused, but hopeful. When Stephen turns away from him without any acknowledgement, he's crushed. But can he just give up hope on something that he has longed for his entire life?
