So this is the whole story if I remember correctly?
A boy finds a girl trying to commit die. He stops her from doing so and asks why she wants to do it. She said that she had this sickness and anyone who sees it can see death, plus ppl with the sickness want to commit die. The girl tries committing die a few more times with the boy stopping her and eventually he gets tired of it so they both decide to do it. So they both say their goodbyes and jump off a building. The boy dies but the girl doesn’t because the guy had the sickness the whole time and the girl was basically death.
