A bench covered with moss, a fluttering yellow butterfly, and the magnificent acacia tree that bears the promise of infinity coincide with the universe in the unfolding of events to the tragic past life of two souls condemned by religion and society. When Valdis Constelo discovered the infinity sign with letters M and A, which had been beautifully carved for more than a century on a tree trunk, fragments of memories of his past life started to emerge. He recalls of a guy begging for help as he was drenched in his own blood. But what he could clearly remember was the promise that he made for him. Calypso Imperial recalls the same event when he first entered Universidad de Don Manuelo. But two years later, he saw a student at the main entrance who got almost hit by a car and that triggered him to clearly recall a guy who died in his arms and made a promise that they will be together in their next life. Is this the fulfillment of the promise once made by a priest who was condemned and stoned to death 127 years ago? Val and Cali will once again fight for the battle that Manuelo and Antonio have lost for over a century. Will history repeat itself? Or they will recreate a completely different ending for the promise to prevail in this progressive era?
