Hello, first of all, I sincerely bow my head and apologize for the discomfort you experienced during your learning process with my lecture. Above all, I am deeply reflecting on the fact that I failed to provide satisfaction for a lecture you chose with your precious time. In an era where change is so rapid, my desire to provide more insights beyond simple skill transfers led to long-winded explanations, and it seems my ambition got ahead of me. This is due to my own shortcomings. I will take the feedback you provided to heart and strive to repay you with clearer lectures in the future. Thank you sincerely for leaving such valuable feedback. Once again, I am sorry.
