I can not remember ANYTHING about BSD if I'm being honest so I'm trying to reach into the depths of my memory to something would used to tick me off.

I think how ship-orientated BSD shippers/fans were? Like being unable to see a character past their most popular ship and only seeing them as an extension of whoever they're shipped with, like they're unable to be seperated. Nikolai and Chuuya were the biggest victims of this with Fyolai and Soukoku.

Also Chuuya is arrogant and should be allowed to be arrogant more often
