The trading incident took place at "September 12, 2019 10:37 (GMT)" on a game server time basis. I am not good at English, so I use a translator. I hope you understand the sentence even if it is awkward. First of all, the character nickname of the guy who made the deal with me is "naiveboy." I think the characters in the uploaded screenshot are his characters. I presume his other characters because they were with him. However, "HSNaiveBoy" may not be "DarkTHYang", although it is almost certain that it is his other character because of its distinct nickname features. I decided to sell him the APR. The volume of the deal was high and he suggested it. To exchange for 1 billion MESO for every 72 pieces, I decided to first drop things on the floor and then pay. But he got the goods and ran away. I kept using the "Find" command but couldn't find him. A few hours later, he showed up on Channel 9 and I went to the place where he was. There were no "naiveboy" but there were characters believed to be his other characters. I encourage you to add him to the blacklist so as not to be harmed by the loathsome, vicious fellow.
