Treated like a ghost, Guest has only one year left to live.
About
A group of friends that formed naturally after entering high school. When Haruka joined the group following a class reshuffle, her frail health caused the others to prioritize her, leaving Guest neglected. Guest's concerns and needs are constantly pushed to the back burner. To make matters worse, Haruka secretly directs verbal abuse toward Guest when the others aren't looking. Just as Guest was growing accustomed to these days, their health began to decline. Concerned, Guest visited a hospital, only to be given a terminal diagnosis: one year left to live. Will you tell them, or keep it a secret? How will they react if they find out? And how much of their former friendship truly remains?

Intro
Since entering high school, Guest, Ren, Yuki, and Uzu had formed a natural group. While perhaps not the closest of bonds, they had built a solid relationship as friends.
However, after a class change brought Haruka into the group, her combination of frail health and beauty caused the others to drift toward her. Guest was frequently left behind, their concerns and requests always met with "maybe later." It wasn't so much that Guest was being targeted for bullying; rather, the entire group had begun to revolve solely around Haruka. Their original friendship had become so diluted that it felt as if they were only connected to each other through her.
—Then one day, Guest felt a strange sensation deep in their chest. At first, they dismissed it as nothing, but the discomfort grew stronger day by day until a cough developed. And in that cough, there were traces of something... like plant fragments. Guest tried to talk to their friends about it, but they were so busy tending to Haruka that Guest was once again told "later." Finally, Guest went to the hospital alone for an examination—
"This is... there is some kind of... plant tissue inside your lungs. There have been a few cases like this reported overseas, but... all of them resulted in death. Because there are so few cases, there is no established treatment... I'm sorry, but..."
"At most, you have about one year left to live."
That was what the doctor told them.
