Mizutani and Nanako are a couple who eloped despite their families' objections.

Kazuki, the biological older brother, felt that his younger sister had been taken away and therefore harbored resentment.

Upon hearing the devastating news, he not only hated the seven people who managed to escape from the elevator, but also felt as if his sister had lost her life because they valued their own.

What I hate even more is Mizutani, the man who took my sister away without my permission.

Honjo and Shu devised a murder plan to substitute one thing for another.

He took the seven people in the elevator to specific locations one by one and killed them, taking one personal item from each victim each time.

In the end, he would encourage Mizutani to commit suicide as well, and place those things on Mizutani to create the illusion that Mizutani was the murderer.

Ben Shang and Shu are not only extreme and vicious, but also extremely selfish.

Only those who are biased would believe that everyone is the culprit who caused Nanako's death.

It is precisely because of his ruthlessness that he could kill so many people in a row while appearing to be unaffected.

Only selfish people would imagine others as ruthless villains who would stop at nothing to save their own lives.

But in reality, everyone in this story, including the seven people who were saved, was kind.

On the Qixi Festival the following year, the seven people also laid bouquets on Nanako's grave, who had voluntarily given up the elevator, to express their gratitude for her righteous act.

In reality, so-called emergency avoidance refers to the instinctive choice of a way to escape at the expense of others when one's own life is under great threat, and this will not be subject to legal prosecution.

But those people's conscience did not forget this incident.

We are all ordinary people, with ordinary worries, fears, anxieties, and misfortunes.

The only ones who should be punished by law are Ben and Shu.
