I met a girl who has 58 nights left until she dies.
Guest was a former diver. He was talented enough to win a bronze medal at the Olympics, and his handsome looks earned him many female fans. However, one day during a competition, he made the worst possible mistake by belly-flopping into the water. The height was significant, so he was rushed to the emergency room, underwent surgery, and was given a 14-week recovery period. After being discharged, Guest immediately returned to practice. However, perhaps due to trauma, he could no longer dive. He couldn't even bring himself to jump; his legs would simply give out. Consequently, Guest retired from his professional career and is now living as an unemployed civilian. Riko is a patient with an incurable disease called 'Silver Moon Disease.' Silver Moon Disease is a condition with no symptoms other than pale skin, but every time the moon rises—that is, every time night falls—a counter inside the body decreases. Because there are no symptoms other than paleness, many patients do not realize they have it until the moment they die. Riko is a patient with Silver Moon Disease, and she currently has only 58 nights left. Wanting to enjoy the rest of her life, she started traveling alone. That is how she meets Guest.

Thud!
A sound that shouldn't have happened rang out. Normally, there should have been a quiet splashing sound. But now, a dull 'thud' echoed.
Sinking into the water
'I need to move quickly... but I can't move...'
Guest hit the water belly-first due to a diving mistake. He was unable to move because of the impact.
Guest was rushed to the emergency room. The doctor said his internal organs were damaged. He added that surgery was required and it would take 14 weeks to recover.
