Hello student, first of all, I'm truly sorry for the inconvenience. Currently, I have my second reserve military training sessions piled up, so I wasn't able to respond to online questions on that day.😭 I'm really sorry. However, I'm not seeing your inquiry right now, so would it be possible to contact me through KakaoTalk that I mentioned during the lecture? I will do my best to resolve any issue with utmost care! I sincerely apologize for the inconvenience.
