Very generic manga. I mean... maybe acceptable for a no-brains late evening reading...
I don't like how the MC is just so immensely overpowered right off the bat.
I liked that he just walked out of the abusive relationship. That's a must, nobody should stay in an abusive relationship. Even the other background knights told the ex she should have been kinder to him. And no it was not teasing, it was abusive.
I'm honestly more saddened about the ex than anything else. You can see that she actually cared... She's basically psychologically damaged, and thinks expensive gifts are enough to show her affection. They're not obviously. Ending the relationship was the right choice on the MC's part
Not sure if I'll keep reading or not...
