It could be said that, in fact, Zhao Chi was just PUA'ing Sun Qingqing. He wanted to make Sun Qingqing feel that it was only with him that she truly found mutual love, and that Zhang Zheyuan, becoming what he had, was entirely a result of his own doing!
Zhao Chi wanted Sun Qingqing to believe that her affair had nothing to do with her; it was all Zhang Zheyuan's fault for not being good enough. Only between her and Zhao Chi was there true love, while Zhang Zheyuan was nothing but a third party interfering in their romance!
Moreover, even if Sun Qingqing really did get pregnant, Zhao Chi never considered taking responsibility. He just hoped that in the end, Sun Qingqing would marry Zhang Zheyuan. That way, Zhao Chi wouldn't have any burden, and then Zhang Zheyuan would have to support their child, while he and Sun Qingqing could continue their secret trysts.
