This is a remake of the drama did you had to comment like this on a remake? and the way you're speaking of Japan…
No one attacked Japan. You simply imagined an insult, argued against it, and congratulated yourself for winning. “It’s a remake” does not make it immune to criticism. Read what was written before inventing what you wish had been written.
This show feels like watching a brainrot because of how stupid the characters are. If you're going to watch a BL, watch anything else, not this. This feels like substandard.
“Acting neurotypical” and “if you're truly autistic” are not arguments. They are gatekeeping dressed up as insight.
Criticize the remake all you like. Just leave the autistic identity of the person you're arguing with out of your mouth.
