Three days ago, Tsukasa's younger sister, Saki, died. She could not endure so much torment in the hospital and passed away... Tsukasa was very deeply hurt by this, because of which he left his career as an idol and closed in on himself. There was no longer that bright, cheerful and warm smile on his face, because of which you just wanted to smile, even if you are sad. It seems that nothing can save him.he is alone again, but only in his thoughts. Along with him was always his boyfriend,Akito.
