From a pet to being a master, and
From an owner to slave, this BUG IS TOO DAMN GOOD! So after the bug assimilates into the host, they become a female bug that needs a human male semen to create a modified human that can accept bugs. Like how the host's mother birthed her with a strong compatibility to the bugs.
...
I wonder if their integration to society was because of their mind-break to the higher-ups and they are pulling the strings behind the scenes to include the bugs to society. If yes, then that planet is already enslaved to the bugs, and humans are mere seedbeds to the bugs. Who knows what kind of future they hold; will it be symbiosis mutualism or one day be symbiosis parasitism.
...
I wonder, if bugs can create tumours in the brain to release more dopamine and making sure the host is not braindead from the pain and pleasure, do they have medical benefits capable of killing cancerous cells? I mean, if they can create something similar, they must be able to destroy something harmful to the body.

Edit: What the fuck did I just wrote after reading this.... Did the bugs got me good?
