Lucas after visiting his home had been pretty much cooped up in his house to the point that he could teach 'how to be lazy' class and if there was a system that recorded one's achievement, he would've been a champion.
His daily routine had already been in disarray. In the academy, he would stay up late at night for self-training and would sleep for 2-3 hours.
Before sleeping he would activate the mana breathing technique and when he woke up, he would feel refreshed and all his aches and pains would be subsided greatly.
But it was the opposite now. His body was now aching due to laying in bed like a lazy bum.
Living in his house where everything was brought to him, to the point that his mother even wanted to feed him, and only stopped after Lucas' pleading. He could feel that he was becoming a sloth.
