Redo of Healer

It is said, one who possesses a healing class can do nothing except for treating wounds. That they’re unable to fight, or protect. Such kind is impotent on their own, left only to rely on others. Others, who can do whatever they please with them. There was a boy, who had faced that miserable truth, yet by the time he did, it was already too late. His life had been ruined to shambles, further existence would be in vain. And yet, he wouldn’t give up, even though everything that was left was to redo his own life.
