Thank you so much! Have a great weekend! :)

(Just some personal comments. My son taught English in Busan. It's where he met his American girlfriend/now wife. They have fond memories of South Korea. They have since taught in Turkey and Kuwait, and will move to Shanghai, China to teach next year.) Yesterday, my friends and I went to Busan to see a night sea ["see a night sea" is OK, I think, but "see the sea at night" sounds more natural.] It took about two hours to get there. As soon as we arrived there, we took some photos near the sea. And then we went to a famous restaurant. We had spicy spaghetti, cream spaghetti, and a really thick pizza. Oh! We also had soda! They were so delicious! ["They were so delicious" refers only to the sodas. If that's what you mean, fine. But if you mean the food too, then "Everything was so delicious."] After that we walked along the night sea. [I think leave out "night" here.] When ["After" is better here than "When"] we walked about an hour, we found that there was a path with many beautiful cherry blossom trees. Although it was really dark at that time, we took many photos. Then we went to a beautiful cafe and had sweet drinks. ["sweet drinks" is OK gramatically, but it sounds a bit odd. Say more specifically what you mean by this. Sweet wine? Sweet soda? Coffee with sugar in it?] I think I spent so much money [rather than "so much money", either "too much money" or "a lot of money" sounds more natural] yesterday. And I feel bit tired now. I'm getting ready for today's classes. I think I'll arrive ["at my"] dormitory room late today.
