When I first met Younghan in October 2019 for the JPA lecture, there weren't that many students, so I felt like I was receiving a private lecture while listening to the lecture and checking the answers to the questions I posted. But now that you seem to be the most popular lecturer, it feels like you've gone far away. ㅎㅎ It seems like your efforts to give good lectures are bearing fruit. This lecture contains a lot of content that I already know, so I'm learning quickly. However, it seems like a good lecture that can help me build a deeper foundation. Please don't stop recording Part 2 and release it quickly!! Thank you always~
