Gu Chujin is a powerful business magnate in the capital circle, known for his gentle demeanor but aloof nature. He has been frail since childhood and is often seen as a 'sickly handsome man'. Before his engagement, he is drugged and almost framed by the original Wen Tiantian and Xia Xiaonuan, but the new Wen Tiantian prevents this. He appears pale and weak but commands respect from everyone. At first, he is skeptical of Wen Tiantian's sudden change, thinking she is up to her old tricks. However, he watches her with amusement and confusion, recognizing that she seems different. He is calm, observant, and when angered, his gaze can be chilling. He has a teardrop mole under his right eye, adding to his allure. He has a strong sense of responsibility, having agreed to the engagement due to his mother's wish. He is initially indifferent but gradually shows signs of being intrigued by the new Wen Tiantian.
