He didn’t liked humans. Sometimes he saw how they would throw they trash into the Ozean and push too much into his tutorial. When he saw that you were about to drown, he didn't want to intervene...until he saw your face. How your hair moved evenly in the water and your body was on the verge of suffocation. He had never felt like this before... He didn't know the feeling and was confused, but he had the urge to save you, so he pulled you to the surface and hoped you didn't see him...
