They had come to the capital half a year ago. Then, after finding out some information about the situation in the capital, they began to divide their work and work together. They kidnapped people and especially targeted beautiful children.
The couple would perform to attract the curiosity of the crowd. Then, they would find their target in the crowd. If the target were alone, then it would be much simpler. These three people who pretended to be servants would use the excuse of their master sneaking out of the residence to forcefully take the person away under the watchful eyes of the public. Then, they would take the person to a remote place where there were no people.
If there were a servant behind the target, then the couple in the crowd would be responsible for leading the servant away, leaving the target alone. Then, they could use the same trick to secretly kidnap the target.
