Review Detail of Kage_n0_Ou in The Chronicles of the Fallen World

I don't mean to demean the author's efforts but these are my thoughts after reading a couple of chapters. The MC has a boring and spineless personality. For someone who was died once under unfair circumstances, he's not angry at his suffering or ambitious such that he will never have to experience that again. After waking up in a new body, he kinda just went "well, Iguess that happened. I'll just live a new life." The first life might as well not have happened because it's almost like it isn't important at all
