The pheromones suppressor chip, in this history is a chip not pills or injection like the others Keke7607
As far as I remember there are pills and injections. The chip is just more effective because he might forget to take the pills. Also, the chip has an app to check the pheromones, although he never used it. I think the app can also pause the suppression if the omega wants to get pregnant.
In chapter 5 he said he doesn't want to be a bata because he has to live with a chip inside his body.
What kind of chip? Did I miss something?
