Zheng Manman was undoubtedly very bold. Knowing full well that the other person was not interested in her, she pulled such a stunt relying entirely on two things.
One was the man's inherently restless and wandering mind. She simply did not believe a guy could remain indifferent when faced with such seduction from her. Even if he didn't like her to begin with, when a girl like her behaved this way, even the firmest moral resolve was bound to loosen a bit—especially since she was his pretty, blooming sister-in-law, a combo multiplier at maximum effect. The moment there was the slightest crack in his defenses, her chance would arrive.
Her other source of confidence came from her understanding of other aspects of young men. Many guys had a strange quirk: they tended to be quite lenient with women and would often swallow their grievances just to save a girl's face. The younger the guy, the more prone he was to this. Even if she upset him, he would look out for her dignity and keep it to himself. As long as he didn't call her out, there was still room for maneuver.
