Huang Hui and Shen youchu barely interacted with each other. Even when she was in rocket 101, Chen hansheng never brought Shen youchu to group gatherings.
First, Shen youchu was not used to crowded occasions, and second, Chen hansheng was worried about causing unnecessary trouble.
Huang Hui didn't know that Shen youchu actually had a younger sister who looked quite similar to her.Huang Hui also didn't know that Shen youchu was studying for his master's degree. However, they were separated by the rain and hadn't seen each other for a long time, so she had mistaken him for someone else.
However, when she arrived at the counter, Huang Hui could still tell that this girl wasn't Shen youchu.
First, the height was wrong. In Huang Hui's memory, Shen youchu was at least 1.7 meters tall, while the cashier at the milk tea shop might only be around 1.65 meters.
Secondly, there were very obvious facial features.
