Even though the concept is nothing new stil love the story, love the world design, the power progression of MC feels a bit too much like a plot armor, a little bit, but still ok. The most disappointing is MC's characterisation itself, it's too confusing, but giving MC the benefit of the doubt that he is still not and too many things going on, it is acceptable. Also, I love that unlike most of this genere where all the girls MC comes across throws themselves at him, this story is different and doesn't paint all girls like airhead bimbos. But the dissapointing this is MC's unhealthy obsession with Bran and his not so ex-girlfriend Sierra(from pre time travel) is pure pathetic, this just destroys a good story. I mean I understand that as per MC's vengeful character to dislike Bran for defeating him but his obsession with Sierra doesn't make any sense
