In which episode did Xiaobei and Haizao completely break up?

In episode 26, we broke up completely.

Su Chun received a notice from the unit to withdraw the lawsuit, and Haiping happily told Haizao the good news. Haizao wanted Xiaobei to invite her sister and brother-in-law to have a meal together to celebrate. She was cooking noodles, so she asked Xiaobei to use her mobile phone to send a text message to her brother-in-law. At this time, Xiaobei was surprised to find Song Siming's text message: "Haizao is back. Don't get married." Xiaobei felt hopeless and angrily cursed Haizao for being shameless, and finally ended the relationship.

Haizao walked to Song Siming's unit in despair. When Song Siming revealed that he had rescued Su Chun, Haizao was very grateful and resumed his relationship with Song Siming. In the end, Haiwei became a professional mistress... Oh, this woman!
