A new social system in meeting one's death is implemented via new euthanasia laws; Yihoo, who is in dire pain from stage 4 heart cancer, chooses to die by euthanasia.

As Choi Hanki leaves for Yonder, he leaves behind one last message, "There is nothing left, so there is nothing to lose;" this convinces Jaehyun and she decides to go to Yonder as well.

When Yihoo realizes that Jihyo is no longer growing, he is hospitalized at the protocol center; while in search for Yihoo, Jaehyun meets Dr. Jang Jinho and learns about the flaw in the unchanging Yonder.
