Di Yan's change began when she fell in love with a seiyuu she had never seen before. She also fell in love with him inexplicably. Unknowingly, because of that person, she embarked on a completely different life than before. A person as sane as her has actually become what everyone sees as a "star chaser". However, she is not crazy or obsessed with that person. She doesn't even know what the owner of the voice looks like. What she pursues is a voice that cannot be touched. She wants to protect that clear and pure voice, the voice that has given her hope for the past three years. She wanted to spend her whole life supporting the owner of that voice, and she also wanted to fill in the lyrics for that voice. In order to make that voice sing the lyrics she wrote, she traveled to Japan to study. In order to wait for Orion to appear, after countless rainy and snowy days, she finally waited for the voice actor she liked - Orion. With just one sentence, she knew it was him. The story between them begins here, but they can't end it even if they spend their entire lives...
