I studied at an academy as a non-major and luckily got a job at a company, but since I lack the basics of Spring, I thought a lot about what I was doing and why it ended up like this. After taking this lecture, I learned why it's used like this! I think I learned it so enjoyably and fun while taking the lecture, but coding was boring when I didn't know anything and used it, but after taking the lecture, it became so much fun. While taking the lecture, I also saw Younghan giving the lecture in an enjoyable way, and I had so much fun that I didn't even realize how time passed! Thank you so much for the enjoyable lecture!
