The film Wuhai stars Huang Xuan and Yang Zishan, Huang Xuan plays Huayang and Yang Zishan plays Miao Wei. They are a couple in the play.

Huayang comes from a small village, and he needs to do everything by himself. After getting married, he asked his father-in-law to take a sum of money to do business with his friends. As a result, he was tricked into borrowing money outside, and the debt collectors also came to him. Miao Wei's family conditions are very good. In fact, Huayang's parents disagreed with her, but they got married anyway.

However, her parents-in-law have always disdained Huayang, and they put pressure on Miao Wei on the phone. Miao Wei originally wanted to tell Huayang that she was pregnant, but because Huayang received photos of her friends on her mobile phone, they quarreled. Huayang also gave Miao Wei the recorder in the driving recorder and asked him if he was with his former classmates.

Both of them don't trust each other, so when Miao Wei later said in the car that she was pregnant, Huayang didn't believe it was her own child. When Miao Wei was angry, he said that the child was not his. In fact, Miao Wei has made it very clear by sending WeChat to the male students in front, and there is no deviant thing between them.
