There Is No You on the Other Side of Yigui

A pair of lovers fell into silence due to the cold war. The heroine issued an ultimatum of "see you at the end of the tracks", but the hero was stubbornly late and only empty railroad tracks were left when he arrived. After that, the heroine completely disappeared and married someone else. The male protagonist learned about the marriage beside the old subway tracks and finally realized that what really killed their love was not the fierce quarrel, but the cold silence day after day - it was like a dull knife, silently cutting off all the warmth and possibility.
