Dear, Mr. Pun
We have sent the money. We'll send next money on the 20th of March as we promised you. And would you send us an e-mail about the first itinerary of your expense until around the first day of April?: we'll really appreciate if you can send the itinerary of your expense around the first day of each month.
If you have further questions, please contact me whenever you need.
May you go on making a progress!
sinserely, Seo Ae
PS: By the way I'm not Mr.. I have never heard people addressed me as 'Mr. Yoo!' since I was born.^^ I am Miss. Yoo.
