[1V1+Shuangjie+The protagonist is the villain] #awakeMuseless Master VS Paranoid and sickly girl Naigouli# Among the many urban rumors in Xia Gang, there is such a ridiculous but true story. Six years ago, a strange creature bureau suddenly opened in Dongcheng District. The person in charge claimed that there were strange creatures hiding in the crowd, and they were arrogant and manipulative. At first, everyone laughed it off and thought it was just a bluff, but then—— Howling demon dogs; A strange and unpredictable mansion; A plane that went out of control for no apparent reason; The vampire in the old city castle; The victims who came back from the dead... Everyone (crying): You didn't say the urban rumors were true! ! ! * Mu Yan, the head of the Alien Creatures Bureau, whose age is unknown and nicknamed "Young Master", is most interested in solving unknown mysteries for his own entertainment. Until one evening—— She met a homeless man who was even more mysterious than she was. He had lavender eyes and an uncanny face, and it took a lot of effort to meet him. This, this, this, how could she control this? "Since you don't have a home, then come home with me." From that day on, there was a new member of the Alien Biological Bureau. However, what Mu Yan never expected was that he just took in a homeless man who was covered in mystery, but ended up losing himself in it! ? "Yanyan, you agreed to give me a home, but you can't break your promise~" Mu Yan: ... You can pretend that I didn't say anything PS: 1. The protagonist has no distinction between good and evil, and is chaotic and good; 2. Imaginary fantasy, please do not take it too seriously; 3. The plot is the main part, and the relationship is supplemented. The canine boyfriend has a canine boyfriend, and the ending must be 1v1.
