人の専攻まで知ってるし、学内だとは思うんだけど、Uyangaって誰だｗｗ
うやんが？

以下メール本文

Hello,
Happy New Year!
Can I have a question, please?
I think your major is economics, therefore I thought maybe you have any economic books you don't need anymore. Can you give them or sell them to me, please?

Thank you,
I will wait for you response,
Uyanga
