@vvIdzz their personalities r different. Soho got the innocence and carefree side. And 4 got the more alert and cold side. And what other boy u r talking about? The one in the club? It's just another random xbt robot so he's not important. Soho transferred himself to that robot so that he can get information and protect his original body at the same time. 4 is the highest ranked xbt robot cuz he directly works with the government. And same with Soho. Other xbt robots r lower ranked so they r random in this story
