In order to raise his brother's medical expenses, dog trainer Du Yan accepts a commission to accompany Ye Lingyuan, a wealthy young man who has closed his heart due to past trauma. With her patience and gentleness, she melted the ice in his heart little by little and soothed his anxiety and paranoia. Ye Lingyuan gradually opened his heart, but when he got better, Du Yan left silently. When they reunited unexpectedly three years later, he had already fallen deeply in love with her. Even in the face of the status gap and many obstacles, he always guarded her firmly. In the end, the two transcended the world and the past, healed each other, and stayed together for a lifetime.
