A young man named Lin Tian met the lonely and helpless girl Lin Xiaotian by chance, and out of compassion, took her home to care for her daily life. For the convenience of external explanation, outsiders simply regarded them as a harmonious pair of unrelated younger and older juniors. Day after day, living together side by side through the passing time, the two young people gradually grew familiar with each other, and affection quietly sprouted. The two originally had no kinship ties whatsoever. In the process of getting along, they slowly came to terms with their true feelings, crossed over the misgivings brought by worldly views, and gradually walked toward a romantic bond belonging exclusively to each other.
