It's short so I can focus and watch it, and the explanation is good and step-by-step.... But the only thing I wish there were was an example file.. I want to try it once, but the teacher says, "Okay, I'll proceed with what I prepared in advance~" but what about me...? Me, teacher ㅠㅠㅠ I'm doing it on purpose xd and following along, but when you suddenly do that, I'll just turn it on and watch the lecture ㅠㅠㅠ
