Please and thank you for teaching me so much. I've loved learning Korean and experiencing your culture and lifestyle. I've been blessed to have been able to travel to Korea and to have met so many wonderful people who were so willing to show me a part of their lifes. I was a mere stranger, but they were brave enough to take me in and open their hearts. I will be forever thankful for all those who made my experience such a heart-warming one. 🥰🥰🥰🥰🥰
