Two Years Left in My New Life

The Male Protagonist Works Silently, Is Misunderstood by the Female Protagonist, Leaves Sadly, and the Female Protagonist Regrets

Cleanse both mind and body, preferably a short film

The Protagonist Is a Substitute, Who Is Cruelly Abandoned, and Is Later Diagnosed with a Terminal Illness, Leaving Him Disheartened.

Later, they felt very guilty and tried their best to compensate him, but he did not accept it. Note (No heroine!!! No heroine!!! No heroine!!! Say important things three times)

The Protagonist Is Desperate and Wants to Die. Everyone Feels Guilty for Him and Wants to Try Their Best to Compensate Him.

Is There a Male Protagonist Who Is Terminally Ill, Cruel, Violent and Desperate?

I want to watch something like "Only three months left to live, they came to beg me for forgiveness!" Book.
