Due to him not having an affinity, he was bullied numerous times by the Elementalists in his class.
Although he wasn't the only one in the academy without an affinity, he was the only one without a mana core foundation.
Fortunately, his parents quickly intervened, withdrawing him out of the academy dorms before the situation got even worse.
They also complained furiously to the academy's authorities, using their power to their advantage.
However, that still didn't curb it completely.
There were still a few students who kept bullying him; talented Elementalists whose parents had even more influence than his.
Since the academy never really considered him a student, they ignored most of the bullying.
No matter how many times he complained, they turned a blind eye, advising him to withdraw if life at the academy was that unbearable.
