Zhou Xiangnuan has liked Chen Qiuyang since she was a child, but she knows that this feeling cannot be expressed verbally. Chen Qiuyang was admitted to be a pilot and went to another city. Zhou Xiangnuan and Chen Qiuyang had not seen each other for six years due to their studies. The first thing they did after they reunited was that Zhou Xiangnuan accompanied Chen Qiuyang on a blind date. Zhou Xiangnuan witnessed his breakup when he refused to express his love to the opposite sex, and did not dare to let Chen Qiuyang know her thoughts about him. He just behaved obediently in front of his so-called sister. Chen Qiuyang knew that Zhou Xiangnuan's university was in his current city, and he took great care of his sister. The relationship between the two gradually got closer during their daily interactions. It was not until Zhou Xiangnuan's suitor Luo Shi appeared beside him that Chen Qiuyang realized that something was wrong with his feelings for his sister.
