He is a retired interstellar god of war who works as a physical education teacher in a kindergarten in the city and works part-time as a substitute god of marriage - he uses children's crayons to draw red lines. The new music teacher has the same face as Bai Yueguang, but has no memory of him. What's even weirder is that the red thread he controls is wrapping them around crazily, and all her past love records are blank. When the mastermind behind the scenes attacks on the parent-child day, the God of War has to rekindle the war to protect a garden of cubs. Little does he know that she, who is playing the piano next to her, has gathered the same power as him at her fingertips... This time, he has to protect not only the children, but also the truth about her that has been deliberately erased by the world.
