In a large underground research room, there is an "artificial forest". Every plant here is transplanted one by one by researchers from outside. They did this entirely for the sake of Research Body No. 6—June. Because June was born in June, June was brought here, and June would have a very high fever on June 28th every year. Various coincidences led the staff to name her June. One day, June, who understands the language of plants and animals, finally escaped from the research institute, but as soon as she came out, she traveled to the Flame Ice Country. She met the first man she saw in her life: Ye Mingyou. (Because June is an orphan, and all the people in the institute are women.)
