In Please Answer 1988, Paula wants to take the law exam. Why did she break up with Shan Yu?

In Please Answer 1988, the emotional relationship between Paula and Shan Yu has always attracted much attention. Although they finally got married, Paula broke up with Shan Yu while preparing for the judicial examination. Why?

First, Paula, who is sensible, actually always wanted to study law-related majors when she was in college, but because her family was in debt, she studied a major that could be studied for free and got a scholarship. Many people may think that Paula has a bad temper when watching the drama, but in fact she is a very delicate person and has been quietly paying for her family. Then, after the debts at home were paid off, she had the idea of studying law. She has always been a very hard-working person, and she also hopes to pass the law exam very much.

Secondly, the same surname is the same as BenPaula and Dou, so Paula, who is studying law, should be very clear that people with the same surname can't get married, which is not allowed or recognized in Korea 1988. Moreover, she was arrested in a reactionary demonstration before, so this is also an obstacle to Paula's law inspection. She also knows that she has to work harder to succeed, so she can't be distracted to maintain her good feelings during this period, and she has no time and energy, because she has to devote herself to legal study to succeed.

Thirdly, Deborah's sister Paula is Deborah's sister, so in this play, all the children in the hutongs of Deborah's generation will respect Paula as their sister. At the beginning of Sun-woo's intention, Paula euphemistically rejected Sun-woo because of her sister. Although they are together, when they first got together, even when Paula went to study law, it can be said that Paula herself was not sure whether she liked Sun-woo or just regarded him as her younger brother. Paula always asks Sun-woo to show her respect. In fact, from the point of getting along, it is also obvious that Paula still doesn't know her heart.
