The grammar and writing is all fine... But instead of Antares, as written in the title and also in the story. It feels more like a teenager reincarnated in the MCU with a System that gives him Antares's powers... I mean, he has no pride or arrogance that was shown in the novel or Manhwa, nor the cunningness, nor the serious demeanor that comes from people who all have lived as long as Antares...
