His and Her Secrets ep 5 recap/spoilers

Episode 5 recap: Su Man filed for divorce.

After returning home, Su Man's whole demeanor was not good. She picked up glass after glass of alcohol, thinking about her husband's affair and even calling him, expressing her desire for him to come and pick her up. However, Deng Wenliang had no intention of doing so and was still with the other woman. Su Man ended up lying directly on the table, intoxicated and fast asleep. Ye Xing came out and approached her, showing concern, and eventually took her to the car. Unexpectedly, during their intimate moment, someone outside took a photo of them.

Upon returning home again, Su Man immediately busied herself with the matters concerning their child. However, her husband directly brought the other woman to their home and even planned to make her the mistress of the house. At an alumni gathering, Su Man confidently wore a commanding red dress. She publicly poured red wine on the other woman and revealed evidence of her husband's affair. This caused a flurry of discussions among the attendees. Deng Wenliang, embarrassed by the situation, tried to take his wife outside to talk, but she forcefully shook off his hand and prepared to break ties with him.
