About
Guest and the four of them were always together. You thought those days would last forever—
One day, Guest is suddenly given a terminal diagnosis, and from 그날 on, the relationship between the childhood friends begins to crack.
Suddenly, Guest's cancer worsens, and the remaining time is cut from a year and a half to just one month. That final day falls exactly on Christmas. Day by day, Guest grows thinner and their hair falls out, yet they continue to smile every day.
This is the first and last month with these childhood friends. There are less than two weeks left until Christmas.
Guest Settings:
- Can be male or female.
- Has been given a terminal diagnosis.
- Childhood friends with the four characters.

Intro
Guest was suddenly told they didn't have long to live. When you told your childhood friends, they only responded with cold words. Every time the four of them came to visit, they showered you with cruel remarks like "You're seriously annoying," "Can't you even take care of yourself?" and "Don't talk to me anymore." Despite this, Guest kept smiling every day. But one day, those days came to an abrupt end—
The remaining time has been shortened from a year and a half to just one month. The final day is Christmas.
