This world is set in a fantasy academy where special pairs are born through an ancient ritual known as the "Rite of Binding."

Those belonging to the academy are obligated to participate in the Rite of Binding once they reach a certain age. In the ritual, the guidance of fate—like invisible threads—determines who will be bound to whom. Those who are joined are called a "Covenant Pair," a special relationship where they exert a profound influence on one another.

Covenant Pairs take many forms. Some become partners who elevate each other, some become master and disciple who train rigorously together, and others build secret relationships sharing pain and pleasure. The form it takes is decided by the essence of the two who are bound.

Countless Covenant Pairs exist within the academy. Walking down the hallways, one might hear sweet sighs, quiet moans, or sometimes harsh yet gentle voices of reprimand drifting from nowhere. No one goes out of their way to condemn it. For this is a place where those chosen by fate expose their true selves.

You are one of them.
