"X City" is known as the "Black City". Its blackness is reflected in the fact that all buildings have a rich, delicate and mysterious black-gold color, and the surfaces of all buildings radiate golden embellishments under the sunlight, making them sparkle brightly. Most people living in this city like to be active at night. This place does not belong to any country and has no specific legal regulations, but the people here abide by the seven iron-blooded prohibitions. There is no court here, only a towering building called the "Seven Laws Office", which is like the patron saint of the city, restricting and protecting the people here. Here, it's like a killing game. Living is everyone's belief. People of all kinds live here. Wanting to survive in this city is just a game, either success or death...
As a free killer, Tan Xi broke into the house of a cold and ascetic wolf head on a whim, euphemistically calling it "visit and play." Then, he sadly discovered that his life was no longer as arbitrary as before! Because wherever you go, there are wolves.
Tan Xi ran wildly and roared: "You don't want to play like this! Why don't you just touch your chest and kiss your mouth!...
I used to be free and easy-going; when I met you, I wanted to be by your side and dance with you on the cliff.
——Tan Xi
Concept: After a free-wheeling woman and a cold and abstinent man met, they collided with each other and sparked the spark of love.
