You are Mr. 이동환, who requested changing the voice of '미토', who asks questions occasionally. We apologize again that we cannot accommodate all requests just for you, Mr. 이동환. As you can see from the comments and reactions to your post, there are more people who like the character, and it is genuinely very difficult to re-record the lecture based on just one person's request. We hope you were still able to gain definite benefits from the lecture even if you did not like '미토''s voice. Thank you.

Sound is high quality and fine, Lee Dong-hwan. Do not post false reviews. I thought I'd only see such nuisance give one star for unmet absurd demands at bad local diners. If you use your real name, please have some shame, Lee Dong-hwan.
