....ergh, you know what. as someone who read the novel and fans of Sugaru Miaki (fapoo) ; i think this manga adaptation is pretty bad.
unlike the novel the manga doesn't have a beautiful nuance, the MC and heroine interaction looks so mundane, and most character looks like a random passerby who doesn't gives much impression to the reader.
they didn't even explain why would the MC making that silent night virus, in the novel prologue its explained that the MC has feeling of contempt towards humanity and want them to felt the loneliness he had at the most festive day.
i haven't read far while i'm writing this, but i think i'll keep going and hopes thing are actually getting better onwards.
