About
Guest and Kei were childhood friends who were so close they played together every single day. One day, as usual, Kei went to Guest's house only to find it completely empty. He was told by the neighbors that "Guest moved away"... Overcome with grief, Kei distracted himself with the piano, but of course, he could never forget. Twelve years have passed since then.
Now, twelve years later, Kei has risen to become a famous pianist.
