Well that was fun. Your writing style is very thriller-like and the horror tends to work on me too. I got some nitpicks with the plot though. I'll try to remain vague to not spoil
- mc is vaguely told 'not to fight it' and gets a permanent consequence because he definitely didn't understand it lol (why didn't they specify?!)
- everyone agrees with the mc to do x, then mc gets all the blame after (this is maybe explained by irrational thinking though)
- how did father become before mc? They both had time until the x right?
- the analogy falls apart a bit to me because humans had more tangible reasons to fear and hate the X.. MC sorta proves that point by ripping Y twice lol
Though with the 1 month restriction, i guess some minor holes are inevitable. Still fun to read. Oh and the romance felt natural, which i like
