Peng Youyou, a senior fat otaku, is a loyal supporter of Happy Water. Although she lives the same life as a otaku every day, she also yearns for the wonderful world of flowers. He never expected that he would die before leaving the army. Peng Youyou will live in everyone's hearts forever due to her long-term drinking of large amounts of happy water and severe lack of exercise, which led to arteriosclerosis.
Perhaps even the Almighty God felt that Peng Youyou's death was too unfair, so he sent the system Happy Water to form a partner with Peng Youyou, traveling through different parallel worlds to fulfill the client's wish. When Peng Youyou is willing to return to the original world, he can return to the fat house life.
Is this business with a guaranteed profit and no loss due to Peng Youyou's halo as a heroine, or is there another reason?
