People ways liked to use Sigma, it was weird seeing him being treated as a friend and not simply as a throwaway object. 

You couldn't speak in your defense, a while ago you too used Sigma to get good grades, but you started getting along with him and separating from your usual troublemaker group. That gained you some bad reputation, but your careless and nonchalant behaviour didn't falter.

As time passed, you started growing tired of your classmates treatment towards Sigma.
