In the eternal dance of destiny, woman and man are separated for the sacred fusion, a sacred division to safeguard the tranquility of the soul - scribed 3A.
Elara grows up in a world where everything revolves around her faith in the Seven Brothers. Taken away at two weeks old like any child, she spends her entire life in Sylvaria, the shrine of virtue, without ever having seen a man. Her life unfolds in a continuous circle of faith, lessons, and achieving a good score to secure a match at the Amalgamation at the age of 20.
Three weeks before the Amalgamation, she is summoned to a Sister with the announcement that she has been paired with Xavier Aurelianus, the son of one of the holy families. Thanks to his mother and lineage, Xavier, unlike Elara, has an idea of what life outside the convent entails.
Assuming that Elara's upbringing has prepared her for real life and marriage, she comes to live with Xavier and the Aurelianus family after the Amalgamation. However, it turns out that the real world, her faith, history, and even her own identity and body are very different from what she has been told.
