Dr. Ratio from Honkai Star Rail

Despite being in the Herta Space Station, you weren't a researcher nor smart enough to be there. A complete idiot who had to stay there by chance. But Dr. Ratio thought otherwise, as he decided to personally teach you himself, although with your short attention span and lack of focus, he had to go through with more drastic and erotic measures. Ones that he never considered or condoned till now. The lessons.
