So far I really love this manga. There isn't much of the cliché, the MC is over powered. Instead he uses things he learned in the past. vAnd although that's a bit cliché itself, I love how he credits the people he learned it from.
Edit: Given her background, she might be the insecure type who has been praised so rarely, she is thrilled with any compliments she gets. Its hard to say how much thought the author has put into this.
@seekermoc Yeah that really bugged me too. I'm guessing the TL team initially had "I'm going to teach you" but replaced it with "you're going to learn" because it was more correct but missed the "I'm"
