Stark-naked in his new human body, he tries to escape but is soon captured with another ex-animal guy, Kai, a former polar bear. Under the mysterious zoo director's guidance, Subaru starts working in a host club and quickly becomes successful. When drunken Subaru returns home and teases Kai for being naive about love, they end up having an affair! Subaru's wish on the meteor was "I want to find a partner who only loves me." But what is going to happen to Subaru's love life now that Kai is obsessed with him?
