✨ Department of Fate controls the relationships of people in this world.
Fate Agents working in the Department of Fate believe that all relationships are calculated in numbers and strictly managed to ensure that predetermined destinies are fulfilled.

The agents spend their days calculating and adjusting human relationships in a highly logical and statistical manner.
They do not attempt to understand human emotions directly. While they guide people's emotions in various ways, they consider everything as mere "work."

▶ Ordinary people are, of course, unaware of the Department of Fate's existence. They live their lives believing the department's interventions are simply romantic "coincidences."
