Ép. 4: Nabi rompt avec Doki pour la protéger, ce qui entraîne son arrestation et son voyage solo vers le Paradis.

4

Compared to the rest of the series, Step 4 is filled with violence and turmoil. It chronicles the conflict between interspecies relationship supporters and opponents. The neighborhood is covered in derogatory graffiti. Various people are yelling at Nabi and Doki and kicking them out of places for being an interspecies couple. Meanwhile, the rabbit holding the sign in Step 3 has started a full interspecies movement, which includes members of both species and the Jjintta Set. However, the anti-interspecies movement is far larger, though notably segregated between rabbits and cats. They attack Doki while she is playing with a few of her animal friends. The Hedgehog tries to defend her, but they are both badly hurt, and Doki is hospitalized. Nabi, who is scared that she will be hurt again, decides to break up with her for her own safety, going as far as to put up an anti-interspecies sign on his house. Doki, who is trying to help the hedgehog while it lays dying, decides to get two plane tickets for "Paradise," presumably a place where interspecies relationships can exist peacefully. She hopes that she and Nabi can live there together. Il-ho sees this, and decides to confront Nabi, literally punching him in the face. However, this starts a riot between interspecies supporters and opponents, and they all get jailed. The hedgehog dies. Afterwards, Doki tries to call Nabi, but he is unable to answer, due to being in jail. Doki gives up, and decides to go to Paradise by herself. (Source: Newgrounds Wiki)
