It seems to me.
A green ring floating above your head.
It is visible.
The D-day of death that comes to you.

“That guy Ryu Dam, he’s a voluntary extrovert.”
“You’re the only one bullying our class? That’s really funny.”
“I wonder what it will be like.”
“Do you think it’s cool to talk bluntly?
Ugh, it's creepy!”
In middle school, I overheard people talking about me in the hallways and bathrooms, and they said my reputation wasn't good.
Well, that makes sense.
Because I was always alone at school.
He didn't smile much and was indifferent when anyone spoke to him.
Sometimes, I would react coldly to those who tried to cross the line under the guise of 'friend'.
Some people called me a socially awkward kid, while others said I was suffering from chuunibyou.

I couldn't trust people anymore.
Everything felt pointless.
Even though I knew what the number of friends meant, I couldn't stop the death.
That fact left me feeling helpless.
The ability to see the D-Day of Death wasn't some special tool that could save the world like Batman or Spider-Man.
It was more like a punishment that made me realize how weak and useless I was.
The thoughts in my head piled up and gradually hardened into conviction and belief.
No one can escape the certain death.
I too can only see when the D-day of death comes, but I have no part in that death.
So, to avoid feeling like you want to help someone in a clumsy way, you should not form relationships with people in the first place.
I decided to live my life pretending not to know anything, pretending not to see anything, because I wouldn't be able to see the D-Day of someone who had nothing to do with me.
(…) not to have any more relationships with people.
Stop trusting people.
That was the only way I could protect myself.

“Do you see any numbers?”
"yes?"
I was so startled that I reflexively jumped up.
“That’s right.”
The old man licked his lips with a confident look in his eyes as he watched my reaction.
His lush beard swayed with the movement of his lips.
"hmm……."
The hairy man cocked his eyebrows with a serious expression, then poured water from the bottle in his hand into a disposable plate.
Then he crouched down and placed it in front of the heart cat.
“Sir, can you see D-Day too? Is that so?”

"i like you."
Somiso spoke immediately.
“I know, I told you.”
“Ha, no… I like you more than bread.”
"…… what?"
As I was startled by the sudden words and just stared blankly, Somiso avoided my gaze for the first time and lowered her head.
And then, with a nervous expression, he moved his lips as if he was about to say something, and then he finally opened his mouth.
“Dam-ah, how about we… become closer?”
--- Among the "new variables"

The man spoke in a cautious voice, stroking his lush beard that resembled a lion's mane.
“Humans are not usually altruistic beings who would readily give up their lives.
If we have to be exact, it's closer to being selfish.
Wouldn't it be against human nature or providence for such a person to risk his life for others?
Well, maybe such a mutant behavior could cause some change in the cosmic order and create a miracle.
What I mean is, the sacrifice of life is something so difficult that it transcends the realm of human beings.”
The meaning behind the old man's words, as he slowly recited rules I had never known before, was clear.
I guess that means shut down.
Unless I'm willing to risk my life to save Somiso.

Amidst the chatter, I silently bit into my coffee straw.
And that was the moment when I raised my head without thinking.
The D-Day floating above Lee So-hyun's head suddenly changed.
The number that was quite long was reduced to '5'.

What is this again… … .
My mind became dizzy.
I immediately turned my gaze towards the hairy man.
The man's hand was pouring coffee, but his eyes were staring straight at Lee So-hyun's head.
It was certain that the old man, like me, had witnessed the change in Lee So-hyun's D-Day.
