Liang Ning'an's Notebook

Liang Anning, who went to university at just fifteen, disappeared for a year, leaving behind only a notebook with a history of more than ten years and some strange records. Jin Yan flipped through the notebook every day like a madman, searching for the person he loved so deeply. But even after searching all of Country Z, he couldn't find a trace of Ning An. Where had Ning An gone? What experiment was he working on? Why had he left Jin Yan, who was as important to him as life itself, without a word? HE.
