"I know you're in there! Open this door, or I'll knock it down!" A loud, angry teenage male voice could be heard all across the passageways.
Gustav's eyebrows repeatedly twitched as he heard the voice, "I know that voice," He muttered.
Kom! Kom! Kom!
The banging on the door increased even more after the person heard no response coming from the other side.
Gustav made a low hmph sound and continued his meditation.
'He came seeking his own end... But I can't attend to him until I am finished with this,' Gustav said internally as he blocked out all distractions and continued to focus on what he was doing.
The person who happened to be at the door knocking was none other than Gustav's younger brother, Endric.
He stood at the door and kept on knocking for about thirty minutes, and still, there was no reply.
