The man did not look in the direction where Richard was, when he heard Richard calling his best friend's name loudly. But he was focused on getting Nicholas back to his senses, so he paid no attention to what Richard was doing in front of his wardrobe.
Because the way he is doing now is the most powerful way to get Nicholas back to his consciousness.
With his clawing his index finger into the back of Nicholas' neck, the goal was for the man who was unable to control his emotions to come to his senses and remember all the events that had happened to him before.
The man in the plaid shirt was Roran. Don't know where it came from, but he managed to save the man who was now standing with a shaking body and cold sweat when he was about to be attacked by his best friend.
Fortunately, Roran quickly managed to dispel Nicholas, who was about to smack Richard in the face.
