Riku Kambayashi was a university student, who wanted to become a novel writer. Minami Maezono was a university student, who wanted to become a singer. They fell in love at first sight and married while they were university students. Now, Riku has achieved his dream of becoming a bestselling writer, but Minami hasn’t achieved her dream of becoming a singer. Minami somehow feels disconnected from her husband, who is busy with his work. One day, a comment by Riku triggers a big argument between them. When Riku wakes up the next morning, he finds that Minami is nowhere to be found. He goes to the publisher for a meeting, but he figures out that he now works as an editor of a literary magazine. More surprisingly, Minami is active as a popular singer-songwriter. Riku is confused by everything that has changed, but he gets busy to get his life back.
