The MC escapes and,upon meeting his brother, discovers that he betrayed him, the wolf saves him just in time. We then see the wolf’s backstory (he was raised from a pup to be beast without regard for how it would affect his health, and now everyone fears him because he's the "watchman" of them all) His sister (the leader) betrays him and nearly kills him, but he survives and punish her. The wolf's (hormons)condition worsens, and the MC finally accepts him in order to help him.
