Disownment Guidebook [Weekly Short-Short Note]

"I have disowned you."
"Of course I'd disown you, after a movie like that."
"To have my heart shaken like this... no wonder everyone says they'd disown them."

The movie "Disownment Guidebook."
A reticent middle-aged man disowns his son; to summarize, that is all there is to the story, but—

"At first, I thought it was meaningless to go as far as reading a guidebook just to disown someone."
"Who would have thought it was actually out of deep love for his child..."

Yes, the protagonist had a mark appear on him that would lead to death within a month due to a "curse unto future generations" received by his ancestors—and to break the tragedy that had been repeated for generations, he "disowned" his son.

The clumsy man's resolve, which inevitably moved those who watched it.
However, the reason it inevitably made the viewers want to disown others was not there, but—

"...It appeared. The same mark as the protagonist, on me too."
"Everyone who watched it..."

...The movie was pulled from theaters, but the "Disownment Guidebook" containing the procedures for disownment shown in the film is selling out everywhere, causing a scene of utter chaos.
