Niceland is basically about a young man (or an old boy) Jet living a joyful life working at a factory with his girlfriend who he's deeply in love with and vice versa. But shortly after they decide to get married and live together happily ever after her cat, who she has a weird affection for, dies. The girlfriend falls into depression which could (strangely enough) lead to her death and the only way to give her a purpose to live and save her is to tell her the meaning of life.
