Review Detail of Chief_TFGX in Shock! The Spell Is In English!

The title is a little misleading, it should be "Shock! I change the premise of the story as soon as MC starts at the academy" Why did his loyal servant abandon him for a mysterious cult? what happened to the love rune obsessed beauty? What happened to runes in general? All these questions but I still need to ask why the MC literally stole his classmates family after meeting them twice?
