Cheng Chao went to Jiangzhou to study and stayed at a friend's house. By chance, he met Chu Yu, a girl who lived across from his friend's house.
Cheng Chao was an honest man. He secretly had a crush on Chu Yu, but found that Chu Yu had already had a crush on him, and the boy whom Chu Yu liked had already liked a girl. Everyone in the compound felt that they were a perfect match.
Chu Yu, who also secretly had a crush on someone, disappeared for a long time after learning that the boy she liked had a girlfriend. Later, she slowly came out of her grief and noticed Cheng Chao, who had been protecting her from the wind and rain.
Cheng Chao said that Chu Yu will always be the only heroine in his life.
