At first, the code development flowed a bit differently than expected, requiring some adjustment, but as I followed along, it became an opportunity to learn the flexible thinking needed in practice. Thanks to the unique flow of the serial-type lecture, the feeling of building the development process together was impressive, and I was deeply moved by the instructor's dedication and sincere communication. Personally, it was a lecture that re-motivated me during a time when I had many concerns. Thank you!
