Jiangyu was once the brief moonlight in his life, shining on his darkest and coldest road;
Han Yi was the wild spirit when he was young, reckless and flamboyant, leaving scars all over his body that could not be erased. Until he finished crying, hurting and became numb, he became gentle and stubborn again, staying by his side;
Li Yuan is the person illuminated by the moonlight and hugged by the wind.
Concept: There is no romance in reality, so it appears in the story.
