As I have read your thesis proposal. I found it was a very interesting theme and I am pleased to inform you that, I approved that your thesis proposal is possible.
However, please let me give you some comments so that your thesis proposal will be a little bit easier to understand for those who never had a background in such an interesting area (like me)
1. On page 5, you mentioned that one of your objective is to compare the friend's quality preference between Korea and Japan , including china. I found that the research hypothesis in 1. Objective1 is still not clear . It still a little bit hard to understand why you have to compare this quality between those 3 nations ( even though some explanations are mentioned in the thesis proposal)
2. Since one of your objective in this thesis proposal is to compare the freind's quality
between those 3 nations,the details should be provided more, not only in chapter 4.
Hope that my comments will be useful in some way. Thank you very much for your attention and good luck on your exam tomorrow!
