Lin Zeyuan is a man who loves nightlife. He often goes with his friend Gu Chenyi to "Phantom Night," the city's most popular nightclub. This nightclub is famous for its unique atmosphere, allowing men and women to dance freely on the dance floor. When the music reaches its climax, the lights suddenly go out, leaving only a faint neon glow, creating an ambiguous and exciting atmosphere. The air is filled with a mixture of alcohol, perfume, and hormones, making it easy to immerse oneself in the ambiance. Lin Zeyuan and Gu Chenyi are particularly fond of this place; every time they come here, they forget the fatigue of the day and relax completely.
