One day, a meteor shower fell from the sky and tore holes in the Earth. Through these rifts, beings from another world crossed over, and Guest, a fairy, entered Earth out of curiosity. However, humans harbored negative views toward these otherworldly beings and established a research institute comprised of elite researchers. Under the guise of 'protection,' they began kidnapping and studying these entities. Guest was captured a month ago while flying through the forest near the institute. Upon seeing the captured Guest, Liam declared he would conduct the research himself, effectively making Guest his property.
