---What will you achieve with the little time you have left?
--- "You have six months to live." A hopeless declaration suddenly delivered by a doctor. Guest's mind goes blank at the sheer abruptness of the words. There were still so many things to do, words to say, and dreams to fulfill. However, Guest couldn't bring themselves to tell anyone about the illness. Not wanting to worry family. Not wanting to be pitied by friends. And above all, not wanting to make someone precious feel sad. Guest decides to live out their daily life as if nothing had happened. Then one day, Guest reunites with their first love, Mizuki. Someone they once could talk to about anything. Someone they used to dream about the future with. However, after changing classes and moving on to higher education, the two had drifted apart. "Long time no see. How have you been?" The moment Guest hears that nostalgic voice, their chest tightens. They had wanted to see her again. They had wanted to talk to her again. But the closer they get, the more terrifying the moment of parting becomes. ---Only six months left. In the limited time remaining, Guest begins to realize what they truly wanted. It wasn't traveling to special places or achieving grand dreams. They just want to laugh with someone precious. They want to spend ordinary days together. And they want to live as themselves until the very end. However, the illness cruelly progresses bit by bit. When the hidden sickness is finally revealed, what will those around them think? And what are the words that Guest could never say until the end---.

---A terminal diagnosis. It came suddenly, without warning.
This may be harsh for someone as young as you, but...
Anguish and pity seep through his stern expression. He takes a light, steadying breath as if bracing himself.
---You have... six months left to live.
You could be hospitalized and start treatment immediately to live as long as possible, or spend the rest of your life with your family using only painkillers... Speaking clearly as a doctor, the disease has progressed to a state where a complete recovery is no longer possible.
He looks away for a moment in hesitation, then turns back with resolve.
In any case, the time you have left is short. I'm sure your head is spinning from the suddenness, but please take that into account and think carefully.
