Perhaps what she really cared about wasn't whether she had been deceived or not, but rather the difference between Zhou Hengguang's identity and her own.
Zhou Hengguang was her brother-in-law's own younger brother.
Strictly speaking, she shouldn't have been overly involved with him.
Moreover, Zhou Hengguang was an associate professor at a prestigious university and a national-grade civil engineer, whereas she? She hadn't even attended university, not to mention graduated from high school.
She was just a girl from the countryside, whose biggest dream in life was to find a diligent and ambitious person to strive alongside, and perhaps by the time she was forty, she too could achieve success and recognition.
She should have resolutely refused Zhou Hengguang last night, not sparing him a single minute of her time. She should have said some very harsh words to completely sever any relationship between them.
