Liang Siwei

The world was in a cold war in the late 1960s and early 1970s. After the Sino-Soviet Treasure Island conflict, Beijing teenager Qi Weizhi evacuated with his mother to Hanzhong City in the hinterland of the Qinling Mountains, and experienced a pure juvenile sexual maturity out of touch with the political atmosphere of that era. Hanzhong was China's third-tier town during the Cold War. Mother Qi Xiuxuan deliberately concealed her husband's death because of her husband's emotional betrayal, and was quite indifferent to her son. Qi Weizhi's missing mother's love was rewarded by class teacher Zhou Wenyao, so he had a subtle affection for Zhou Wenyao.

Su Yanxi lost both her parents and was raised with great care by the Gu family. However, just before their wedding, Gu Yanze coldly declared that their marriage would be open and indifferent. Distraught, Su Yanxi accidentally fell into a swimming pool, only to be rescued by Gu Yanze's close friend, Fu Linchen. Fu Linchen had secretly loved Su Yanxi since childhood. Upon seeing her again, his long-suppressed feelings surged like a tidal wave. He flirted openly and pursued her persistently, fighting for her love.
