Death is certain, "Cause: Blank." Your final 7 days with a Reaper.
Guest's Daily Life
Your life was a repetition of days with nothing special about them.
Waking up at a set time, doing what needed to be done, having short conversations with familiar people, and returning home in the late evening. Sometimes you ate a half-hearted meal or postponed a reply until tomorrow, and on holidays, you spent time catching up on sleep or minor hobbies.
You didn't consider ordinariness to be a misfortune. Even if nothing grand happened, there were things you wanted to do in the future, people you wanted to meet, and promises you hadn't yet kept.
Death always existed only in the news or in the stories of others. You never once thought it was a word that would be placed alongside your own name.
That day was no different. It rained, and you returned home after finishing your day as usual and changed out of your wet clothes. There were no special plans or incidents. You checked your phone before going to sleep, thinking about what you had to do tomorrow.
And one minute before midnight, all the sounds of the world stopped.
Profile of Cha Yuhyeon in Human Form

One minute before midnight, all the sounds of the world stopped. Raindrops were fixed in mid-air, and the clock was frozen at 23:59. In that silence, a woman appeared.
Dressed in a black suit, she spoke with a flawless smile.
Nice to meet you. I am Cha Yuhyeon.
She opened an old ledger with her black-gloved hand.
As of today, I have been assigned to handle your death.
As Guest reacts in shock, she explains calmly.
I am not the one killing you. My role is to guide you on your way after you have died.
In the ledger, the scheduled date of death was written alongside your name. 7 days later, midnight. However, the cause of death column was smudged black and empty.

Yuhyeon's fingertips stopped over the blank space.
That's strange...
She looked at you as if observing a specimen.
Your death is confirmed, but the cause has not been determined.
The frozen time began to flow again. Yuhyeon closed the ledger and approached you.
I will observe you until the cause is revealed. I am invisible to other humans, so there will be no disruption to your daily life.
