This had lot of potential but after every chapters it gets really more and more annoying. The mc I to op and he us just perfect and knows everything just because of a dairy from the future and ruins most of the part about the manhwa. This companion doesn't have any personality it's like he exists only for mc like his motivation in life is to be be useful to him and to be able to stay by his side, I kinda like his companion but he start doing everything the mc say like a mindless robot it makes me angry. After he gets hisrevenge the story gets less then average the are is meh world building there is none so I say my experience was that of 4-5/10.
