I only have complaints about this story. The female leads are uninteresting and the MC's relationship with them feels so forced, since their entire relationship so far is a contract teacher-student relationship and a lot of kissing/s-x because that's necessary for magic transfusion for some reason?? The MC was also kind of raped by a friendly older sister character when he was only like 7 years old?? To clarify, she isn't an antagonist or source of trauma, she literally just had sex with him for the sake of magic training (but she made sure to mention that the child MC was her type), idk what made theauthor think that was a good thing to add to his story.
All the antagonists are stupid so far. The antagonists are basically just a bunch of people underestimating the MC because he's a commoner (despite him repeatedly showing that he's a one of a kind genius) and holy knights that hate the MC because why not.

The MC broke all the school entrance exams, like one of the exams was just to hit a target that was standing still with magic and the MC ended up creating a crater that would require several missiles to recreate and he still ended up LAST PLACE in school (most students couldn't even hit the target and no one even damaged it)

Alright all my venting aside, It's a very mid story with trash romance and trash antagonists. I wholeheartedly regret reading this due to the love interests and unsatisfying antagonists.
