This is the story of an intense, heartbreaking love that began on campus and was etched into the soul. Su Wanwan, a 20-year-old art student with stunning looks, hides a people-pleasing nature and a fearful heart born from childhood trauma. Gu Yanzhi, a 28-year-old biology professor, has an impressive academic reputation, but behind it lie the obsession and need for control fostered by his family’s dark shadow. Their accidental encounter in the laboratory, followed by his gentle gesture of holding an umbrella over her, marks the beginning of her surrender, and of a carefully woven cage.
