After Lilith came to the realization that the demon/daemon that was tasked with the fate of the entire demon realm was not actually a mere sixteen year old but an old demon in the body of a sixteen year old, she knew that she had to change her methods of interacting with him.
She had been observing him ever since he entered the underground cave, and every decision he made and every action he took was not something a sixteen year old would do.
Normally, she would have chosen to act like a master to Simon if she found Simon worthy enough.
She would teach him several things and guide him on the right path of power to take. She would gain his gratitude, his awe, and before Simon knew it, subconsciously, he'd be reliant on her when it came to certain things.
While doing this, she would also ensure that Simon works hard enough to recover her lost strength.
She would barely have to do anything, yet Simon would still help her regain her strength first and foremost.
