Seven days might seem like a long time, except when you are left, right, and centre all the time. Gold was very virulent with his first heat since he refused to let anyone touch him, except his omega father. Day must have spent seven days locked in his son's room, forcing him to eat, helping him calm down. It reminded him of his first time too, where Foud had taken care of him like that. The Lightning God had once again been incredibly effective, as Gold listened intently to him when he explained things to him.
But Day needed a breather.
These seven days were tiring since he could hardly sleep. As soon as he closed his eyes, Gold woke him up by shaking him and clutching him like a koala on his tree. So when his younger son's hot spell ended, he could only breathe with relief.
"You're going to be able to rest today," Foud reassured, patting his shoulder.
"It is in his best interest to follow the prescription of the inhibitors correctly."
