The two stalkers were actually wearing masks to hide their identity.
However, the moment he saw them, Desther immediately recognized one of them as the waiter of that restaurant from earlier.
Although he was wearing a mask to hide his identity, this man seemed unaware that recognizing a person does not only mean recognizing their face.
For example, as he walked forward, Desther noticed the unnatural movement of his elbow. He was walking with his right elbow tucked in closer to his ribs than his left elbow.
This was supposed to be just an unconscious movement by the man. But for someone like Desther, this was tantamount to announcing his identity right off the bat.
Although his senses had also been enhanced due to his high attributes, Desther actually did not need to use such means to identify the person.
As for the reason why they were following him, it was already obvious enough with their current get-up.
