Hello, donseok.lee. This is the 픗픗 Academy. First of all, thank you for taking the course "Practical Small Marketing (1)". Before taking the course, my definition of marketing changed quite a bit, so I thought it was a good course that changed my perspective. I'm so glad that donseok.lee felt the same way! Please pay a lot of attention to other courses at the 픗픗 Academy. Thank you for your valuable lecture review.
