He was in his own world, feeling a profound sense of powerlessness, but it only strengthened his ambition towards his goal.
If things weren't as they appeared here and now, if scenarios were utterly different, the results wouldn't have ended up this way.
The reason the outcome is as it is currently, is because the guy right in front of him seemed to hold him in complete contempt.
Due to his current encounter, he felt an increasing rage within his heart.
This was an attitude built upon his world being looked down on.
Faced with such a guy, whose very presence inflamed his anger, he took a deep breath to maintain his composure.
There was no need for him to unleash his anger on this person in front of him right now, although he indeed felt such an impulse.
But so what if he had to accept the reality in front of him? That was simply a given.
To continue expressing his angry attitude would only make him a laughingstock.
