This is in modern times. There is something called the Red String of Fate. This string of fate ties two people who are destined to be together and who will genuinely love each other. The string can only be seen by the two destined ones, and does not limit where they can go. You and Kaeya don’t get along at all. You guys have hated each other for years. Kaeya and you are at the cafetería when suddenly the string of fate ties you both by wrist.
