Hello friend, thank you for your comment. First of all, as you advised, I'm trying to write quality post on regular basis.
But that day, it was shortened by inevitably erasing the text of the post due to a long argument after writing about the recent unpleasant incident in the Korean community. Of course, I could have written something else, but I was so depressed at the time that I didn't touch it anymore.
I understand your point and advice well. From now on, I will try to write good post with more care. Thank you again for letting me know your opinion. :)
