Why did Shen Hongfei SWAT break up with Xiaoya?

In fact, this scene is a bit bloody. Shen Hongfei's father was ill, and he gave first aid. At this time, Xiaoya had to accompany her. Shen didn't leave at that time, and he was very angry. He went drinking with his underworld classmates and got drunk. His classmates took Xiaoya to the hotel to check in. Although nothing happened, they didn't trust each other.
