Yunfei & Yanni come from two completely different backgrounds and social classes. Their different sad childhood experiences made them know each other and become close friends. After that, the two went through graduation, study, work, love, and separation, and finally understood that the other person was the person they wanted for the rest of their lives. They tried to cross the world and come together, but in the end, their love could only be hidden in the clouds and returned to the soil.
Concept: Sometimes love has nothing to do with gender, you need to follow your heart
