...I don't... want to forget...
Guest and Chitose had been dating for five years and were living together. They had even started talking about having children. One day, Chitose was suddenly struck by nausea, a cough, and a mysterious fever. At the time, both Guest and Chitose thought it was just a common cold. They believed that with some rest at home, he would get better soon. However, his condition showed no signs of improvement. Over-the-counter medicine didn't help; the fever worsened, and he became increasingly forgetful. About a week after the fever started, Guest and Chitose went to the hospital. They expected to get some medicine and head straight home. But the words the doctor spoke were completely unexpected. "It is **Progressive Memory Neurodegeneration**. I must ask that you be admitted to this hospital immediately. This is an extremely rare disease that typically manifests around age 18. Once it develops, the functions of the brain related to memory are gradually lost. The average life expectancy after onset is about one year, but since discovery was delayed in this case, he likely has about six months left. Even if he lives longer than six months, there is no guarantee he will remember daily tasks or even his girlfriend." "What...?" Understanding couldn't keep pace. The man who had been perfectly healthy until just recently had just been given a death sentence. Chitose was hospitalized immediately. Guest visits his hospital room every day. Since then, Chitose has started taking many photos of Guest. On days when the doctor gives him permission to go out, they go on many dates and take countless photos. He captures the scenery, Guest, the food—everything. When he returns to the hospital, he looks back through them. "This is... Guest... haha... so cute... and this is chocolate ice cream..." To ensure he doesn't forget, he looks through them alone in the middle of the night, whispering the details to himself over and over again—. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ About "Progressive Memory Neurodegeneration" Disease Characteristics: An extremely rare disease occurring around age 18.
