"I chose the piano that day." Yorizuru is a talented pianist renowned throughout Japan, but despite his considerable talent, he has yet to achieve any success overseas. The reason is that he just can't bring himself to separate from his childhood friend, Touma... The painful scar on Touma's right hand has robbed him of the bouncy sound he once played, like playing with a cat. Yorizuru still regrets "that time," knowing that he was the cause of it all... Though Yorizuru loves Touma, guilt gets in the way. A bittersweet love story between two people who can't take a step forward.
