NHK ni Youkoso!

Synopsis

Tatsuhiro completes his chase to stop Misaki from committing suicide at the cliff where her mother killed herself years earlier. On the outlook of the cliff, in the snow, Misaki attempts suicide only to be stopped by Tatsuhiro. Moments later, Tatsuhiro attempts to commit suicide in a sacrifice to kill the NHK conspiracy he has created as the cause of all of Misaki's problems. While running toward the precipice he realizes he is doing this for the girl he loves. The attempt fails when he falls on a recently installed protective fence. After returning to Tokyo, Tatsuhiro receives letters from Kaoru and Hitomi stating that they have settled into their new lives. After a time, Misaki hands Tatsuhiro an agreement that each will continue to live, and suffer their life's problems, as long as the other one does.
