Encore ga Sankai

Popular singer Yoko Nito is secretly married to Rui Fuwa, her talent manager, but only the company president and her family know about it. Being a top artist while making an ordinary family with the love of her life will be a difficult balancing act. Yoko is determined to fulfill her promise to Rui Fuwa, to become a singer whose encores will continue to echo long after the music is over. Finally, at her first major concert at the Budokan, she finds her own answer.
