Such a dumb*ss story(● ̄(エ) ̄●)

Is there a possibility that the teacher is a close friend to mc's biological father? Because she said that mc's personality is just like "that person". Or perhaps is the teacher actually his biological mom ( ̄∇ ̄") Since in early chapter, we can get a glimpse that only noble can do magic, so it is sure that mc has that noble's blood. So i think the teacher might have connection with mc biological parents.
Still waiting for the nephew/niece ╮( ̄▽ ̄)╭
