A man who holds large military power and has great achievements, because of an accusation without proof, destroys his whole clan and family, leaving his only child in the hands of traitors? yeah.... right.... what kind of forced generic drama nonsense is that?....

Protagonists love interest practices a generic technique that will make her lose emotions, and he will have to make her overcome that and remember their relationship blah blah blah, like in hundreds of other light novels.

Most infuriating is that later when he is pretty much one of the strongest people in the world, in situations where people he wants do defend are attacked and could die, he "heroically beats up" the attackers and lets them go... and let's not forget that he witnessed the extermination of everything that was important to him as a child and was later tortured for years. Someone like that either breaks or becomes a mu*derer, so this writing here is childish babble with a few "cool" martial arts elements. Waste of time.
