In the sleepy town of San Jose, nestled in the heart of Mindoro, a mysterious letter arrives at the local café, addressed to no one in particular. The letter, written in elegant script, speaks of a hidden treasure buried beneath the tamaraw's ancient grounds. The townsfolk are abuzz with excitement, and it's up to our protagonist, Ana Liza, a determined and fiercely independent young woman, to unravel the mystery. Ana, a descendant of the town's founders, has always been fascinated by the legends of the tamaraw, a mythical creature said to roam the mountains. With the help of her quirky best friend, Kiko, a brilliant historian, and Marcus, a charming outsider with a hidden past, Ana embarks on a perilous journey to uncover the truth behind the letter. As they dig deeper, they discover that the secret is linked to a centuries-old pact between the town's ancestors and the mysterious tamaraw. But they're not the only ones searching for the treasure, and soon they find themselves entangled in a web of deceit, betrayal, and ancient magic. Will Ana and her friends uncover the truth, or will the secrets of the tamaraw remain hidden forever?
