Leonor Valenzuela using a pet name “Orang”
Several months later, during his sophomore year at the University of Sto. Tomas, he boarded in the house of Doña Concha Leyva in Intramuros. The next door neighbors of Doña Concha were Capitan
Juan and Capitana Sanday Valenzuea from Pagsanjan, Laguna, who had a charming daughter named, Leonor.
Rizal, the medical student from Calamba, was a welcome visitor in the Valenzuela home, where he was the life of the social parties because of his clever sleight-of-hand tricks. He courted Leonor Valenzuela, who was a tall girl with a regal bearing. He sent her love notes written in invisible ink. The ink consisted of common table salt and water. It left no trace on the paper. Riza, who knew his chemistry, taught Orang (pet name of Leonor) the secret of reading any note written in the invisible ink by heating it over a candle of lamp so that the words may appear. But, as with Segunda, he stopped short of proposing marriage to Orang.
