A person that you really care about. It could be
your family, friends, and people around you. If  something bad happens
to them, you’d be willing to protect them, a sacrifice. That shows how
much you love them, how important they are to your life. If you fail to
preserve them, don’t blame yourself because you’ll only end up drowning
into darkness, nobody would want to experience that in their life. So,
you have to be strong, not just physically, mentally as well.
